Some camping coaches were conversions of vehicles that were no longer fit for operation and these remained static, in some instances "grounded" with running gear removed or on sections of track that were not connected to an operational line. Others retained the ability to be relocated to address operational requirements, which was possible because of the simplicity of the camping-style accommodation and because the running gear could be adequately maintained. Rail vehicles used for accommodation purposes today are generally not maintained in this way and are no longer compliant with current rail technical and safety standards. They may be adapted to a stationary configuration with e.g. mains water, electricity and sewage connections to meet modern comfort expectations and such modification renders them unfit for movement by rail.
