OK, after your comments about mods I acted on a hunch and found turning off Realistic Electric Trains prevented the crash. I don't see why, as it doesn't seem to have anything to do with what's going on, but I'll post on that mod's mod portal page.

Yeah ack there are a lot of mods, but when I looked at the logs it didn't seem to mention any. Additionally the crash occurred when I deleted vanilla wooden power poles.

I'm getting a consistent crash to desktop when placing or destroying power poles. It's not usually the first power pole to be disassembled, but if I load this save and start removing power poles, it crashes pretty quick:
