If I get to interview I've been thinking alot about how I would answer the question of why I want to be a train driver.
I'm currently a bus driver and I enjoy my working environment - working by myself and effectively being my own boss. I love being outside and the variation in my work - no shift is ever the same, although my current company only has routes mainly concentrated in one city I'm often going to different places. I don't mind whatever I work and it's nice to have the variation in start/finish times from 0407-0145.
I'm a bit of a petrolhead and love driving, I passed my PCV when I was 19 and will be 24 this month and I'm still not fedup of the job. The only part I don't enjoy is the way bus drivers are looked down upon and treated by the public - but I've long accepted this is just part of the job and gives me something to moan about in the canteen!
For me being a train driver would represent a development of this. I want to improve myself and my skills while I'm young - as there's a few similarities between the two jobs I know absolutely that I would enjoy it. An office based career isn't for me, and although there are alternative career paths I could go down there's nothing else that captures my imagination more than the railway.
I've got no particular interest in the enthusiast side of it and it's not because I want to drive a train. I can't explain it in any other way that I'm committed to and enjoy working in the transport industry - I want to better myself and becoming a train driver represents the logical step up from being a bus driver. I enjoy my job the most when it's at its most challenging and would relish the opportunity and challenges involved with becoming a train driver.
The money would be a bonus as it would enable me and my family to live a better quality of life and I wouldn't *have* to work so many hours to earn a decent living.
Sorry for the wall of text but it helped me to clarify in my own mind what I might say at interview. Dunno if it would be the answers they look for though.
