Looking for some help before I expand further. Have a 4' x 8' Polar Express set layout. Along with engine (which we run off of iPad), have 5 lighted cars, lighted platform and want to add lighted flagpole and auto gateman. Can anyone provide an approximate total amps needed - and preferably an approximate amp breakdown. This is only a temporary set up for the holidays and am trying to avoid too much wiring - looking for easy set up. The original set came with the DC 54 watt wall pack (ie 3 amps). Debating if I should upgrade to the DC 72 watt wall pack (4 amps) or set up a 180 watt powerhouse to do it all. Some info on line indicates you can hook up both DC wall packs on the same layout. True?
A good amperage estimate will help this novice! (and any other advice to keep things easy and simple...)
