Hi everyone, I'm new to this. I have two Marx train sets from my younger days, a Santa Fe 1095 from 1959 and a NYC 1666 from around 1964. One of these came with a tunnel, which I no longer have. I'm trying to restore the sets, and I don't remember which one it was or really which tunnel it was, as I know Marx made two versions. Is there anyone out there who could help me find out? Thanks
