Normally only one final bill should be prepared against an agreement or work order . But in cases where groups of annual repair works are included in one agreement or work order there is no objection to more than one final bill being prepared on the completion of each group or certain groups.
( e ) M.A.S. Accounts –
This stands for material at site account. This is a suspense head of account that is maintained to watch actual consumption of materials obtained for specific work such materials stores are requisitioned separately by the executive officer and consigned to the site of work. The monitory value of materials consumed is debited to the work concerned through works Register. The balance under this suspense represents materials on hand yet to be consumed.

Q.2.- Describe the various budget stages for review / modification of budget grants, what is the time schedule for the divisions to submit their requirements to the Head quarters at each stage?                                                                                          
Ans.- Following are the Budgetary reviews under taken on Railway during the course of a financial year –
    i.  August Review – This is one of the Budgetary reviewed stages. This is conducted in the month of August every year by all the spending units / executives to see that any modification are necessary in the allotments placed at the disposal at the beginning of the year.
   ii.  The second budgetary review is carried out at the time of submission of revised and Budget estimate. The revised estimates for the current year are shown on the basis of conclusions derived after this examination in respect of revenue expenditure.
  iii.  Modification Statements – Railway Administration are required to review the budgetary position even after the receipts of revised allotment and advise the position to Railway Board in regard to additional allotment required or surrenders to be made during the current year under each head of grant or appropriation. This is done through the submission of modification statements. First modification statement is sent to Board by 1st February and final modification statement is sent by 21 st February.

General Conditions of Contract – Operation of a contract is based upon the various stipulation contained in the General condition of contract. This is in the form of a booklet and forms as essential part of the tender documents and ultimately of the contract documents. It is essential that every body dealing with contract should be aware of the contracts of this booklet. These general conditions are normally applicable to all contracts and can be superseded when special conditions are specially formed and stipulated in the tender documents / agreement.
Special Conditions of Contract – These are the conditions which are not covered in the general conditions of the contract.
The special conditions of contract arise due to the site conditions and the nature of work to be carried out. These conditions are framed by the Executive and the contractor is bound to fulfill the conditions during the execution of specific works and all out general application.
( c ) Revised Estimate and Supplementary Estimate.-

Budget grant/ revised grant (if received)
Budget proportion.
Actual expenditure during the last financial year.
Actual expenditure during corresponding period of the last financial year.
Material modification :-
No material modification in a work or scheme as sanctioned should be permitted or under taken with out the prior approval of the authority who sanctioned the estimate .

( e ) Reappropriation of Funds and Misappropriation of Funds. -
Reappropriation  -   
The transfer of funds originally assigned for expenditure on a specific object to supplement the funds sanctioned for another object is called ‘’ Reappropriation’’.  
Misappropriation Of Fund  -
Misappropriation Of Funds allotted for specific works under capital or Revenue demand but the expenditure is incurred for another work for which there is no competent authority sanction i.e. expenditure is not voted by Parliament, voted by Parliament but not Reappropriated by the competent authority. Misappropriation Of Fund is a major irregularity in financial point of view and may invite accounts as well as audit objections.

Q.6.- What are the various types of leave that an AEN can possibly get ? What are their respective entitlement/ which of these can be carried forward to the next year? What is the maximum limit to which the same can be accumulated?           

Ans.- Various types of leave that an AXEN / ADEN can possibly get as indicated below –

              i.     Earned Leave ( APL ) – Thirty days Earned Leave is credited to one’s leave account every year 15 days on 1st Jan. and 15 days on 1st July. Maximum leave that can be accumulated at any time is 300 days. Encashment of un utilized leave up to 300 days is permissible on retirement / death of an employee.
             ii.     Leave on Half Pay – It is earned at the rate of 20 days for each calendar year . Leave on Half pay can be converted in to full pay on medical grounds and also for approved course of study. The leave converted is called Commuted Leave. In case of grant of Commuted Leave twice the amount of such leave is debited against the half pay leave due. Half pay leave credited in 10 days on 1st Jan and 10 days on 1st July on every year. Encashment not permissible.
            iii.     Maternity Leave – It may be granted to female Railway employees for a period of 135 days on full pay provided they do not have more than one child. This is also admissible in case of abortion / miscarriage to the extent of 45 days in the entire service.

Ans.- ( a ) Under Reamed Piles –
Under Reamed Piles mainly used in shrinkable soils ( black cotton soils ) to over come the effect of differential settlement due to volumetric change in soil effected by seasonal variations. It can also be used for sandy and clayey soils. These are three type –
        i.Single under reamed piles.
       ii.Double under reamed piles.
     iii.Multiple under reamed piles.
The diameter of under reamed bulb is normally 2.5 times the pile diameter and spacing of bulb should not exceed 1.5 times of the bulb. The minimum diameter of piles should be 20 cm. The top most bulb should be at minimum depth of two times of the bulb diameter. Minimum spacing of piles should be two times the bulb diameter.
( b ) CSM –
A new type continuous action 09-CSM tamping machine has been introduced by M / S Plasser & Theurer. The actual work units however which consist of tamping lifting and lining units are positioned in a separate under frame and are moved in a work cycle from sleeper to sleeper.
Two independent tamping units are provided, one for each rail. These are attached to the machine frame by means of vertical guiding columns.  The tamping units are fitted to the satellite Frame.
The tamping units may be for tamping one sleeper or two sleepers or three sleepers at a time depending upon type/model of tamping machine. 16 tamping tools are provided for tamping each sleeper. The tools are arranged in pairs and each sleeper is tamped by 8 such pairs, on both side of each rail. The units are held by horizontal guiding column in order to slide sideways, which allows their automatic centering over the rails in curves.
The tools are vibrated by piston rods pivoted on eccentric shaft driven by hydraulic motors.
( c ) Track recording –
Track recording consists of objective method of assessment of the quality of track with the help of sophisticated equipments. A continuous record of various track parameters is made with the help of the track recording devices from which an assessment can be made about the running quality of track. Using any of the following equipments- normally does track recording
 i.          Hallade Track Recorder.
ii.          Amsler Track Recording Car.
iii.          Oscillograph Car.
iv.          Portable Accelerometer.
v.          Track Recording cum Research Car.
vi.          Track Recording Trolley.
( d ) Railway Affecting Tanks –
Where as per current practice the Public Works or Revenue Department forwards to the Divisional Engineer every year, their inspection reports on the condition of these tanks which are classified as Railway affecting, action should be taken as follows:–
(a) The Divisional Engineer should peruse the reports carefully and mark those tanks which he considers are not in satisfactory state of repair. He should then forward the reports to the Assistant Engineer with instructions that the tanks so marked should be inspected and reported on.
(b) The Assistant Engineer should inspect those tanks and report to the Divisional Engineer details of the action being taken by the Public Works or Revenue Department. The Divisional Engineer should prevail on the authorities concerned to carry out all necessary repairs before the ensuing monsoon.
(c) Copies of the inspection notes of ‘Railway Affecting’ tanks as received from the Public Works or Revenue Department with particulars of date of inspection and notes of action taken or proposed by him should be included in the Register of Railway
Affecting Works maintained by the Assistant Engineer.
Vigilance over Railway Affecting tanks during heavy rains –
(1) the Divisional Engineer and the Assistant Engineer should arrange with the local authorities/village headman in whose jurisdiction ‘Railway Affecting’ tanks are situated to watch them during periods of heavy rain and give timely intimation to the nearest Station Master, if there is likelihood of any tank failing. The Station Master will telephone/ telegraph reports received from village Headman to the Permanent Way Inspector, Assistant Engineer and Divisional Engineer.
(2) When the railway line is threatened, the Assistant Engineer and Permanent Way Inspector shall take adequate steps to ensure the safety of Railway property and staff and arrange patrolling of the line and or post watchmen with necessary equipment at the place or places threatened and advise the Divisional Engineer accordingly.
(3) All the Bridges which are likely to be affected by Railway affecting tanks or other storage works should be provided with a tablet on top of one of the parapets, with the letters RAW engraved on it, followed by an arrow mark pointing in the direction of the railway affecting storage work in question.
(4) If the bridge in whose catchment a Railway affecting tank is located is classified as a vulnerable location, stationary watchmen should be posted during monsoon.
( e ) Over Dimensional Consignment –
Over Dimensional Consignment may be brought out here that the net clearance between the consignment as loaded and the fixed structure should be calculated after making an allowance from the gross clearance of 75 mm for bounce in the vertical direction on a straight track. In case of curved track the following additional factors should be taken into account.
  1. Horizontal Clearance – Allowance for lean due to super elevation and over head due to curvatures additional lurch on curves.
  2. Vertical Clearance – Vertical tilt to be added to the height of consignment.
Depending on the dimensions of the fully loaded consignments after allowing the extra clearance.
( f )  Scour-
The maximum scour depth in a stream can be ascertained when ever possible by actual sounding at or near the site proposed for the bridge during or immediately after a flood. Before the scour holes have had time to silt up due to allowance should be made in the observed depth for increase in scour resulting from-
  1. The designed discharge being greater than the flood discharge during which the scour was observed.
  2. The increase in velocity due to the obstruction in flow caused by construction of the bridge.
Where the above practical method of determining scour is not possible the following theoretical method may be used as a guide when dealing with natural streams is alluvial beds.       D = 0.473 [ Q / F ] 
Where D = Depth of scour below HFL for regime conditions in a stable channel in meters.
           Q = Design discharge in cumecs.  
           F= Silt factor = 1.76 √ m , m is the mean diameter of particles in mm.
( g ) Pressure filters: -
These are just like small rapid sand filters placed in closed vessels. Water passed under pressure such filters are located in airtight vessels. Water from the sedimentation tanks is pumped into the filter by mean of pumps. The pressure varies from 3 to 7 kg pressure. Filters are classified as –
1)         Horizontal pressure filter.
2)         Vertical Pressure filter.
The diameter varies from 0.30 m to 2.75 m and height varies from 2 m to 2.5 m in case of vertical pressure filter. In case of horizontal pressure filters the diameter varies from 2 to 3 m and length up to 9 m. The rate of filtration is 6000 to 15000 Lit. / hr / m2 of filter area. The cleaning is done in a similar way as in case of rapid sand filter. In order to increase the rate of filtration air pressure is generally maintained on the water surface.
These are less efficient than rapid sand filters in removing turbidities and bacteria’s. The quality of water is not good. These are preferred for treating smaller quantities of water and are best suited for swimming pools, railway stations, private estates, individual industries etc.
( h ) ’A’’ Region states under official language Act :-
States coming under ‘’A’’ Region states under official language Act, are as under –
Bihar  ,  Haryana  ,  Himachal Pradesh  ,  Madhya Pradesh  ,  Rajasthan ,  Uttar Pradesh and The Union territory of Delhi .
( I ) Security Patrolling –
Security Patrolling of the specified section is done on special occasions link civil disturbances strikes etc with the object of protect trains against any sabotage etc like tampering of track placing of obstructions on the line etc.
( j ) Gauge Conversion -
All the advanced countries of the world have recognized the need for uniformity of gauge. There are a number of problems that have cropped up on the Indian railways because of three gauges. The evil effects due to the change of gauge ( more popularly known as break of gauge ) are numerous and some of these are enumerates below –
    i.  Inconvenience to Passengers.
   ii.  Difficulty in transshipment of goods.
  iii.  Inefficient use of rolling stock.
  iv.  Hinderance to fast movement of goods and passenger traffic.
Serious problems exist on Indian Railways due to break of gauges but unfortunately the BG and MG systems have developed simultaneously to such an extent the converting the whole system into one uniform gauge at the stage has got deep financial and operational implications. Indian Railways have however recently taken up some gauge conversion projects totaling about 300 rout kms for converting meter gauge lines into broad gauge lines in order to accelerate and remove bottle necks for movement of passenger and goods traffic.

Rail Tensors –
For distressing and permanent repairs Indian Railway have procured a few Rail Tensors either of hydraulic type called hydro stressors or of mechanical type called mechanical rail tensor.
A hydro stressor consists essentially of a hydraulic pump which transmits its force through connecting vans to clamps which grips the rail. In case of mechanical tensor the force is exerted mechanically by longitudinal jacks by means of this force the rail can be pushed or pulled to a desired length. In case of pushing the force should not exceed 30 tons otherwise the track is likely to buckle on that account. The rail are however normally pulled only during the distressing operations. The rail tensor is capable of distressing a rail at any time when the rail temperature is less than distressing temperature.
