Interoperability

Cab Radio standard is based on EIRENE, Baselines and

National Add-on’s

Cab Radios are subject to Interoperability

Cab Radios have to work seamless in each national network

Suppliers have to provide certificates of the European Notified

Body as well as of all National Authorities

Tests, lab costs, preparation of documents and invoices of the

authorities are very cost driving

(approximately 500 k€ for one new Software Release!)

Standard versus specific conditions

Cab Radio functionality is very close to the standards (EIRENE including Shunting

and public roaming as back-up)

On the other hand each type of train or loco has different environmental conditions

Therefore a lot of different types are available from the suppliers
