I am very sure I have seen something like that underside before. I remember years ago I saw something that looked like the plarail s-09 e3 (seen below) at my cousin's house but it was a lot different:  instead of a switch it had a button  (if I remember correctly) and also had an underside exactly like the tram you have. I remember that it would also get stuck on some points like cross tracks on my classic trackmaster tracks. I have not been able to find anything like it since

Anyone know anything about it?
