Now the train set is super cool.....would love to

Now the train set is super cool.....would love to have the money and space to set something as such at my home. I recall a neighbor in NY country back in the 50's set up his entire basement with trains. Back then the track transformers were huge and recall putting white round pills in the smoke stack to watch the white smoke. The sets had that electrical smell and also the arcing of sparks on the tracks, cool lots of memories.
