MARSHALLING
Marshalling:- Marshalling means scientific and systematic arrangement of vehicles on train to meet specific transportation needs such as safety and security , operational efficiency, elimination of delay, optimum utilization of transport capacity and maximum facility in dealing with traffic during run, at terminal station and beyond.
ANTI TELESCOPIC MARSHALLING:-
The marshalling done by using anti telescopic coach is called Anti Telescopic Marshalling. In this marshalling some special type of coach are attached next to engine and in near of the train. The Anti Telescopic coach is so designed that the impact of collision on other part of the train is nullified on negligible.
ANTI TELESCOPIC MARSHALLING OF MAIL/EXPRESS TRAIN
1. Engine + SLR + 2 ATC + other coaches + 2 ATC + SLR
2. Anti Telescopic Marshalling of passenger Train Engine + SLR + 1 ATC + other coaches + 1 ATC + SLR
3. Anti Telescopic Marshalling of Train on branch line Engine + 1 ATC + other coaches + SLR + other coach + 1ATC The SLR itself is considered as anti telescopic coach because both side of passenger compartment of SLR are provided with luggage compartments. The SLR is attached in the middle of the train in the branch line to reduce the delay due to shunting.
a. In case of SLRs having passenger portion on one side, luggage cum brake portion on other side, it should be scrutinized in such a way that luggage cum brake portion is trailing outermost on next to engine.
b. Passenger portion of SLR should be locked if scrutinized next to engine or trailing outermost.
c. In case of newly designed SLR with passenger portion in the middle, there can be positioned in either way.
d. In case of shortage of SLRs, suitable other coaching vehicles or VPU may be provided and in case of coaching vehicle, used as SLR, its doors should be locked to ensure that passengers can’t occupy it.
e. Two ATCs should be scrutinized inside the ATC SLRs at both ends.
f. After providing for Mail/Express trains, all available anti-telescopic/steel bodied SLR should be used on main line passenger train and passenger trains.
SPECIFICATION OF ANTI TELESCOPIC COACH (ATC):-
1. The ATC are designed with stainless steel and are very light weight in comparison to general coaches so that engine can haul a longer train.
2. The under frame, side and the root are made of with single frame.
3. Each corner isproviding with toilets and next to it doors are provided. The sitting berths are provided in between the doors of either ends.
4. The sides are weaker than other part of the coach. Collapsible tubes are fitted under the toilets and under frames. The energy created during head-on-collision is observed by the sides and the collapsible tubes are damaged which keeps the middle part of the coach for the passenger safe.
5. For identification of this coach cross, mark is painted rear the buffer.
6. Coiled springs are provided between axle and bogie which absorb the shock.
7. Each joints of the bogie frame is fitted with special type of Rubber so that fitness of the coach is kept intact and less sounds are produced.

12. TXRs at all coaching and goods “Maintenance and Fit to Run” stations shall examine all goods stock attached to passenger trains, even though the train to which they are attached is not ordinarily examined at that station. At these stations, the examination will be limited to the goods stock only and will be confined to safe to run examination.
13. On such stations where no C & W staff is provided on the terminal stations, the C&W staff at originating station of mixed train will give the certificate for both outward and inward journey of the wagon whether loaded or empty indicating the terminal station.
14. The pantry car should be marshaled in the middle and should be attached to vestibule stock. 15. Vestibule coaches should be attached in one group as far as possible no non-vestibule coach should be attached in between them.
16. All AC coaches should be Marshaled in one group and should be attached to vestibule coaches at proper place.
17. While marshalling the sectional coaches, it should be taken into consideration that if shunting engine is available at the junction station where shunting of the coaches is to be performed, then the coaches should be marshaled in rear of the train.
