Built by CFMF of France for wagon leasing company STS (later VTG), the 50 PCA bulk cement wagons of the PC017B design diagram began entering service in 1982. A further batch of 15 wagons was manufactured in 1985 by another French firm, Fauvet-Girel, and assigned the PC017C design code. Companies such as Blue Circle and Rugby Cement have leased these vehicles during their time in traffic.
