I'm also expecting to start on 14th October. I'm just waiting for the Verifile email and contract now.
I've followed pretty much the same path as Brad1985. I applied to 1TPE in January and got past stage 1, but didn't get invited to stage 2.
I applied to FGW when their jobs came up, passed stage 2 in May, and had a DM interview on 9th July. One of the interviewers rang me a few hours later to tell me there'd be a place for me subject to HR, medical, etc.
When I started applying for train driver jobs in January, I didn't think I had a chance of even getting past the sift. I still can't quite believe I've actually got a job!
Best of luck to everyone else still in the system.
