Thanks to all for the above info
I’ve just passed my psychometrics privately so now just desperate to get any job I can with GWR or XC and apply internally which I’ve been told is the quickest route in, pardon the pun
They both hardly ever advertise. Unfortunately, I inexcusably missed the advert for XC trainee pool in Feb (don’t ask)
I did the tests privately to confirm if I had the aptitude to get through the tests. Having passed, I’m sufficiently encouraged enough to abandon my current job in pursuit of TD now
I assume those already in the industry would concur that the best route in, besides biding my time externally, is to just grab any job with XC / GWR and go for an internal TD trainee role which a few of my contacts at these TOC’s tell me come up far more frequently than externally advertised positions?
