Asymair95 posted:How many power taps (lockons) will a layout of this size need?
The trains will tell you that - they will slow in areas - I would suggest to start with six for the O27 line - two on each side between the ends
two for the O31 - and one for the elevated
Also, I have a zw transformer, and four smaller individual transformers. How many will I need total to run sidings, lighting, accessories, and trains?
Again, it depends on the trains - Use a handle of the ZW (A& D) for each main loop - use the accessory terminals B & C to group accessories by voltage 14v for switches and 12-14 volt for whatever likes that
use a smaller transformer for the elevated line and another smaller transformer as needed if an accessory likes a different voltage
Thank you again for helping a flailing newbie.
