werkspoor built busses before and after world war two. in the late 1940s 195 crossley busses were built for local public transport companies owned by the nederlandse spoorwegen. after that werkspoor did not build any busses, but after seven years it re-entered the market by a request of the nederlandse spoorwegen, that wanted to prevent the big coachbuilder verheul from gaining a monopoly. verheul was able to build busses with a self-supporting body, and nederlandse spoorwegen thought that werkspoor should also be able to do so. from 1956-1962 nederlandse spoorwegen and its subsidiaries received 477 leyland-werkspoor "bolramer" busses. in 1962 werkspoor sold the bus division to hainje in heerenveen, now part of vdl groep.
