LEGO vintage 4.5V Steam Cargo Train set from 1985! set 7722
Yes, this is that set. With the help of parts from my spares inventory (which thankfully included a very incomplete version of this very set) plus a few things robbed from MOCs, I got the thing mostly accurate & complete. The forklift seat is wrong, the wire is too long, and the battery box is missing two small buffers (the latter not mentioned in the video). Otherwise, I think it's right. Best of all, it runs!
