8th – 9 th June Žilina,Slovak Republic

What are pick - up trains?

• Serve on line sections between two technical freight yards on the principle “leave, pick-up or exchange” wagons in intermediate stations

• Technical freight yards prepare compositions in order to minimaze shunting work in intermediate stations

Short description of Simultaneous method

• Advantages – Forming more then one trains at the same time– Faster forming process with minimal shunting

• Disadvantages– Requires appropriate adjustment of the timetable and

more qualified shunting staff– Begins at the moment when the sufficient number of

wagons is gathered for all trains


SIMULATION MODEL

CONCLUSIONS

• The relationship between – the number of intermediate stations (m) and – required number of sorting tracks (k) ( for accumulation

without additional sorting)
