Technical drawings of trams and trolleys

Technical drawings of the KT4 tram

Designs must be agreed upon during the development of the design.
On the windows (in the passenger compartment), it is only permitted to use a sticker (mesh) that affords a clear view of the outside from inside the vehicle.
The roof is always painted gray unless agreed otherwise.
Foreign-language texts must be approved in advance by the Language Inspectorate.
Stickers may not be placed on areas that are dotted in the drawings.
