4CM, one of the 2nd type of Parcels Van, was based on an old body cast I think from Train Bits (please let me know if otherwise) very generously donated to "Glenburn" by my old mate Mark Tregoning. Underfloor detailing is from my own Motor chassis castings. Van is powered by an SEM Beetle wired to the second bogie which, with the recommended weight included, makes for a smooth running and powerful van.
Ps. For the specialists, Yes apparently the VR called them Parcel's Coaches but the signage on the VR's roll did'nt reflect this!
