DV Class

The bulk cement traffic between Railton and Devonport is the largest freight task carried by rail in

Y7 was built by the TGR in 1971, and was used up until 1989 on all kinds of vacuum braked trains around the Tasmanian railway system. After withdrawal, Y7 remained in Tasrail ownership as a source of spare parts for the remaining two Y class locos.

In 2001 the body shell and underframe were rebuilt into a driving trailer for the Railton-Devonport cement trains. In one direction the driver travels in the DV, controlling the pushing locomotive (usually a DQ class) with a portable remote control set. After arrival, the driver loads/unloads the train from the ground, and then boards the train locomotive for the return trip. The loco body contains a small compressor for the horn and batteries to supply the headlight, as well as concrete ballast weight.

Work has been ongoing for some time to convert former locomotive DQ2007 to a second DV unit (possibly for mainline trains where only on TR is required), but as of late 2018 work had not been completed.

Whilst not strictly an (ex-)locomotive, PNT has a second vehicle that is used for leading trains whilst the locomotives propel from the rear. In 2007, the former test vehicle ZX 1 (itself a combination of guards van GV 3 and a recycled tank wagon frame) was retrieved from storage and overhauled to allow the Bell Bay train to be propelled the 5 km from Bell Bay wharf to George Town yard with the shunter riding safely on the "front" of the train. The van is fitted with headlights, an emergency brake valve, a safe work area for the Rail Operator and a diesel generator set. The van trails the train from East Tamar each morning and is returned to the rear for the return trip in the evening due to the light construction of the underframe.
