Introduction
The purpose of this Technical Report is to serve as a guideline for the application of radio remote
control system of traction vehicles for multitraction operation.
The European Standard EN 50239 is applicable for the radio remote control system of traction
vehicles for freight traffic. This standard sets out 14 application examples. It does not include an
example of multitraction operation; it only includes an example whereby a traction vehicle is controlled
by an appropriate driving trailer in a train consist (example 13 of EN 50239).
This Technical Report is based on EN 50239 and provides an indication of the additional requirements
relevant for the multitraction application.
1 General
Multitraction is used whenever
– the tractive effort of the traction vehicle is not sufficient for the particular operational application,
– different independent trains are linked together to form a longer train consist.
In a train consist with more than one traction vehicle, one of the traction vehicles is always the Leading
Traction Vehicle (LTV). The other traction vehicles contained in the overall train consist are controlled
and monitored by the LTV. This arrangement means that communication between the different traction
vehicles is necessary.
Communication can be achieved by means of a cable link or a radio link. A radio link is for example
necessary whenever there are wagons between the traction vehicles and whenever these wagons do
not have any communication cables with appropriate infrastructure.
Commands are generally sent by the operating personnel only to the LTV.
If there are wagons between the traction vehicles, the effect of longitudinal dynamic effort and braking
behaviour must be taken into consideration during r
