RE: EU Directives for Locomotive Switching and Communications Systems

That's right,
We recently did some compliance work on a radio system for the channel
tunnel. It was necessary to combine the test requirements of the railway EMC
standard for telecoms (EN 50121-4) with the exclusion bands and performance
criterion from the radio standards (plus a couple of other tweaks).

The railways have their own standards and Directives. There is an
ongoing problem of compatibility between these and the RTTED and EMCD.
Look for standards issued by CENELEC TC9X and IEC TC9.

EU Directives for Locomotive Switching and Communications Systems

2003-01-06 Thread Dave Clement

Does anyone know what Directives would apply the electronic switching
control systems and communications systems used in railway systems.

some of this equipment would be installed on the locomotive, some in a
control center some in train stations. I would thin the LVD and EMC
directives would apply or is there a directive specific to this type of
equipment. Any communications systems that use the airways or PSTN would
fall under the RTTE, but is there anything if the communications is via the
rails.

Thanks!
