I think a lot depends on the person..... and what they want etc....
Signalling wise, there different types ie lever frame, NX and VDU, and within signalling different rosters that can cary greatly from box to box...
I can see a one man box (my friend works in one), grade 4/5 can be quite stressful, hard work etc..... especially if it is the 7th night shift in a row for that person!!!!
Then again, you have grade 8/9 signallers who sit in their comfy £1500 leather chairs, watching ARS route the trains whilst they sit back and drink tea whilst earning 80-100k a year!!!
As someone said to me driving might seem glamourous, but how will you feel walking along the cess at 3am, in the middle of winter, -3 temperature and raining, climbing into a train cab to start work....
Similarly, can you handle being inside all day, looking at a computer, or working on your own, dealing with situations as they arise!???
I for one love my job as a signaller and wouldn’t change it... i love the problem solving aspect. I’m on a 12 hour roster and just come off of a 7/8 day rest days off in a row, to work 3 12 hour shifts.... am I stressed or overworked?? Not at all... challenged yes, situations can be stressful when dealing with them, but once they are over, you can relax again! , but I’m not overworked.. and like a driver I take nothing home with me the moment I leave my panel........
I applied for both signaller and driver roles and got through to the DMI for a driver before I accepted my signaller role.. would I change it? Not at the moment.. I feel I have the best of all worlds, a great rewarding job, that pays very well, challenges me yet does not overly stress me out, plenty of time off (on my 12 hour roster) and when I leave work I leave work at work!
Whatever you decide you need to do it for you, not what other people think! Only you can decide at the end of the day!!
