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.
