We'll be running a bunch of MTH PS1 and conventional stuff on our layout. We are powering the layout with a combination of KW and LW transformers, and we'll have manually switchable "block" zones. Blocks are run off the same bus so they're not independent power districts. There WILL be different power loops, but that's separate from the blocks.
Lionel apparently recommends a lock-on (we'll be soldering) after every three or four track splices. We will probably do that, we might stretch it a bit though. I plan on running distributing all power from the KW to each block, first through a SPST switch for each block, then on a power loop with several track connections within each block.
Some of you guys recommend putting the TVS as close to the track as possible. Would it make sense to solder a TVS at EVERY track connection point? If so, I feel like I'm going to have a hundred of them. So my plan is to put a TVS right at each SPST switch or each block and connect between SPST and the common (U) bus. Or should I open all my locos and put them directly in the locos? Just connect the wire from the roller to the chassis ground?
Or is that overkill, and I should just connect the terminals at the transformer and be done with it?
