In my experience, depot driver, or SHUNTER/ driver as it is really, is nothing like being 2/3 of the way to being a mainline driver. It is a shunter's job, with limited aspects of the driving role added on. Anyone from that background, would need a full driver training course. I'm guessing you are a depot driver on the GE, where things seem to be slightly different, ie you are in a line of promotion that eventually takes you mainline. Back to the Dark Ages!!!!
re-training on traction and basic rules though is totally pointless unless traction
type is different as a DD is more than competant on traction.
Other than that they are COMPLETELY different roles. Just like a DD can't do a mainline drivers job without further training, a mainline driver couldn't do a typical MDD job without further training. (At least at my TOC)
DD's get to do some aspects of driving which mainline drivers never get to do. I wouldn't call it "limited aspects of driving added to a shunters job". I find that a bit insulting. At my TOC, MDD's very regularly move swingers, haulers, half-units, put units back together, moving units that are under-going heavy repair/mods, and perform moves around a complex unsignalled yard on your own avoiding conflicting moves, these are things that a lot of mainline drivers in my TOC never get to do.
When you consider that DD's also do fuelling/tanking/toilet unblocking/CET / DP Duties / Shunting / Prepping / engine oil & coolant, and almost constant fault-finding & constantly doing safety-crit comms via radio, that makes the two roles even more different.
They both also require different skills so one person who is suited to one role may not be suited to the other.
I can't believe this topic comes up so often!
Why not compare MDD to something else for a change.
As we've already had a discussion about applying for qualified positions as a depot driver I was curious as to what your thoughts were on applying for a trainee drivers position as a current depot driver.
Scenario is you took a depot drivers position but have a goal of mainline, you won't get mainline for a while at your current location and there's no chance of a transfer. There are trainee driver positions going closer to home and you want to apply. Would this give you an advantage? Something tells me maybe not?
From the TOC's point of view Depot drivers are expensive and difficult to replace so this may hold you back applying for a mainline role within the same TOC. It will mean the TOC will have trained you twice on two seperate & expensive courses - something they are keen to avoid!
But when applying with a different TOC they will be more than glad to take you on as long as they're not on the "old mates act" and as long as you don't say something stupid in the Interview
