I hate having to rerail cars and locos. Especially as they tend to derail on switches or out of reach. This tool makes it easier. It's not perfect, some types of track are not a good fit, but a wee bit of sanding can improve even that. Frankly, the value/cost ratio is so high it's a bit embarrassing. Especially as my fumbly fingers age.

The rerailer works in almost any place on my layout.
