Had some B1s from our company leave in the last year or so and both went into the UK rail industry [different companies] as they were seen as coming from a good safety related background. Both were were pretty junior B1s so weren't on the top pay scale but both were earning above what they were getting paid as B1s within six months of joining and as the UK Government still seems to be happy to fund all the various train companies to run hundreds of "Ghost trains" every day, they still need to be maintained, as does all the infrastructure, so definitely worth looking at.
