At ECLSTS this year, I saw the Piko track bumpers, and bought a handful to try out. They’re made for code 332, but they seem to fit fine on code 250. They’re only about 6 bucks a piece, and dont really have a Euro look
Those are on a piece of AMS code 250 track. They clip on pretty easily. Next up is to weather them with some Sophisticated Finished rust, and add a wood bumper with a metal face.
