I'm a complete rookie here. The last train set I had was N scale about 30 years ago.
Anyway, I have an O scale Polar express set and I am going to build a shelf layout around the perimeter if my kid's room. It will need enough power for lights, smoke, whistles, railroad crossings etc.
How do I get enough power to a layout that big? Will the 80 watt transformer power the whole setup? I was told I should solder or attach jumper wires all the way around, but would like to avoid that.
Someone also told me I can use TMCC and boosters?? How does this work? I don't mind spending the money to do it right (and better)
Any tips would be appreciated.
