A properly cared for locomotive will, after ten years, sell for at least the price you paid for it. This therefore makes this hobby comparatively cheap compared with, say, going to football matches or going to the pub. I gave up beer, fags and loose women (well beer and fags anyway) while saving for my first loco and (over three years cos I borrowed most of the cash) it cost less than three pints a week and an evening newspaper. They cost comparatively less now) I sold that locomotive two or three years ago after 25 years service for around 180% of the purchase price. Once started, this is a cost effective hobby.
