MINIMUM TRAIN HEADWAYS ON RAPID TRANSIT RAILWAYS WITH ADVANCED TRAIN CONTROL AND CONVENTIONAL SIGNALLING

DIE DICHTESTE ZUGFOLGE AUF STADTSCHNELLBAHNEN BEI NEUZEITLICHER ZUGSTEUERUNG UND BEI HERKOMMLICHER SIGNALISIERUNG

This article deals with the problems of rapid transit to and from cities, both urban and interurban systems. It describes investigations into the extent to which theoretical train spacing employing "running with elastic vision" can be achieved with various signal and train-control systems. An ideal system based on headways equal to braking distance and a developed practicable system are compared with four conventional signal systems with long and short protected sections and up to three permissive follow-on signals. The comparison, supported by fully developed formulae and diagrams, shows that the time spacing between trains with a refined fixed signalling system with three follow-up signals and immediate speed control is only a few seconds longer than the practicable train control with cab signals for train spacing equal to the braking distance. With the use of more powerful locomotives, and an acceptable slight increase in journey times, the proposed 90 second interval between trains appears to be a reasonable prospect even with trains of 200 meters length.
