BR Mk1 BCK brake composite coach in BR InterCity 'raspberry ripple' livery.
The BCK was a useful coach, containing accomodation of first and second class passengers, plus a guards' office and small luggage van. In earlier times�brake composite coaches were�used as�through coaches,�so passengers did not have to change trains. In the blue/grey era the BCKs were used on lightly loaded trains, eg. winter services in the far north of Scotland, where the single coach provided all the passenger accomodations needed. Many�were held as spares, as they could be used as a stand-in most other coaches.
