The master scheme, as I understand it, shows great quantities of the new DL locos working in the North Island, sees the enitre fleet of DX's banished to the South Island, and everything else on the mainline (DFT's, DC's, DBR's, DQ's) will be turned into razor blades or ab circle pro's or something just as usefull.
That said though, the company have announced that they intend to give 6 DFT's a major rebuild and tart up for use on branchlines where their light axle loadings will be of benefit, taking the work currently performed by the much older DC's.
Thus! I have shifted my foaming focus from the new and shiney to capturing as many of the old chooks in service as I can before they are blitzed into the history books.
