If you like old 70s diesel models get yourself some Roco E7s. I have a few of them and they will pull more cars than I ever had room for on a layout.
They are as heavy as a brick and have huge motors that take up the width of the shell. (I read someplace that the motors are O scale but I’m not sure that’s actually true.)
The painting and details are horrible but you can usually find them custom painted/detailed on eBay.
I have a couple of the AHM GP18’s. They are very light. As was mentioned, you definitely should add weight but even then, a Roco would probably out pull them 10-1.
