Study Notes
Long Haul Train Operation
- Long haul trains are defined as train formations with more than one standard train.
- They may be empty or loaded.
- Running long haul trains reduces congestion, increases throughput and speeds of rolling stock.
- Trains run on specific named sections (e.g., Maruti, Python) and have a unique color code in FOIS and on control charts.
- The trains are formed at designated stations and TXR (Train eXchange Route) presence is required unless otherwise arranged.
- Train may be split at any station with safety precautions during exceptional or passenger train precedence.
Long Haul Train Composition
- Long haul trains can be BOXN/BCN/container or steel rakes.
- They use single or twin pipe air brake systems.
- Maximum speed of a long haul train is limited to the lower speed of the constituent trains.
- Special T/G boards are used for identified sections.
Long Haul Train Requirements
- Long haul trains use special signaling methods when curves, lengths or visibility block physical signal exchange and Walkie-Talkie communication can be used. If Walkie-Talkie fails, the train must stop.
- loco pilots will be nominated from a certain category and must have adequate experience
- loco pilot of middle loco will follow instructions of leading loco pilo.
- Prescribed whistles are used for communication between loco pilots and guards.
Locomotive Requirements
- Locomotives used must be single or multiple unit (MU) based on haulage capacity.
- For loaded and loaded/empty combinations, leading MU locomotives need at least five operating compressors.
- Middle locomotives in a long haul train are not permitted to charge the brake pipe.
- Rail Brake / Dynamic Brake (RB/DB) of leading locomotives must be in working condition.
Locomotive Crew Details
- Long haul trains begin at the originating station by exchange of physical signals and whistles by guard and loco pilot.
- Loco pilots must be selected from a specified category having suitable experience.
- Before starting after a brake application, pressure must be restored in the engine and brake van confirmed by guards and loco pilots.
- 5 minute release time and careful use of regenerative braking is required.
Carriage and Wagon (C&W)
- Two rakes with separate valid BPCs are clubbed.
- Air pressure continuity test is conducted before operation.
- Minimum BP pressure in engine should be 5 kg/cm² and in the rear brake van 4.7 kg/cm².
- 8-wheeler brake van (if available) is marshalled between the two empty rakes.
- Train detachments can occur due to hot axles or flat tires.
Communication
- Pre-tested VHF sets with spare batteries are crucial.
- Crews must ensure walkie-talkies are operational.
- Trained communication during operation is key.
- divisions must use suitable walkie-talkies for crew.
Operating (Traffic)
- Long haul trains should run on single line clear.
- Air pressure should be created by the leading locomotive.
- Max speed 60 kmph for loaded and stock or loco speed allowance for empty trains, with adherence to other speed restrictions.
- Loco pilots and guards need coordination before and during operation.
