Still time for a morning coffee... The train stops...all change... ...arrived safely as always.

Locomotive Drive Control

One of the leading manufacturers world-

wide of railway vehicles has partnered

with MEN to develop a DIN rail control for

re-ﬁtting, retro-ﬁtting and modernizing its

vehicles. The computer bus and vehicle bus

applied is CAN with a special safety-critical

CANopen protocol.

The connection to the train bus is imple-

mented using a CAN-to-WTB gateway.

Electronics, mechanical design and software

were also developed according to strictly

deﬁned safety-critical requirements. Reliable

vehicle electronics like this system plays

an important role for safe and economical

operation of modern railway vehicles.

It controls, monitors, and diagnoses all

functions during drive and brake operation,

optimizes operation processes and relieves

the train driver.

The system is modular, for instance to be

ﬂexibly adapted to the varying requirements

of locomotives or railcars with different

drives (diesel-electric, diesel-hydraulic etc.).

III based computer board, analog

and digital I/O, pick-ups for the route

sensors and an optional MVB connection.

The monitoring system of this manufacturer

has the advantage of providing a response

channel that allows the permanent trans-

mission of status data of the vehicles back to

the control center. The demand to optimize

mass transit is increasing rapidly, especially

on the growing markets of Asia. Driverless

subway systems are an important economic

aspect. They allow a journey from station

to station that is optimized for energy

consumption and speed, but also a stop at

the station that is precise to the centime

-

ter. Depending on the project up to 500

mobile and especially stationary control and

management systems are needed to monitor

the train on a line.

In a different application a 6U VMEbus

system is the basis for the automated train

control in French trains. MEN is delivering

a PowerPC

based System-On-Module

(ESM™) for this project.

Test Computers for

Subways and Streetcars

MEN supplies a French operator with diffe-

rent VMEbus computers for various testing

tasks on vehicles for urban public transport.

The operator inspects proper functioning

and safety-relevant components of systems

for driverless subways for its own ﬂeet and

as a service for other operators. The vehicle

electronics for subways and streetcars is also

tested in the lab for electrical characteristics,

isolation and robustness.

Monitoring System for

Driverless Subways

One of the leading manufacturers of ATO

(Automated Train Operation) and safety

systems on trains uses standard 19“ systems

from MEN in different projects all over the

world. The redundant CompactPCI
