Firstly, I'd like to say thank to everyone on this forum. It has a been a pleasure reading posts and seeing all the knowledge that is shared on this forum.
I recently bought a train set for my son (Lionel Thomas O-Gauge) and it brought back some great memories of being a kid and loving trains. One of the guys at my LHS joked as I was leaving, saying that the train set was actually for me. My son is only two, so we will slowly be expanding on the set over time. The set came with only a CW-40 transformer. I realized that some of the engines I was looking at may not run correctly with only that transformer. So I figured one of the first upgrades would be to get a bigger transformer. I remember being a kid and seeing my uncle's train set running off a ZW, so after doing research, I decided on that, which should provide power for our slow expansion for a while.
After reading up on everything, I found a great ZW from O Gauge Jim here on the forum, that he had reconditioned (new plug, diodes, rollers, etc). Thanks Jim, it is extremely quiet. I purchased some 1.5KE36CA TVSs from mouser. I also purchased some 7amp TE circuit breakers from mouser, part number W28-XQ1A-7. I am running 16 gauge wire. Gunrunnerjohn had some great posts about all of this. The TVSs are crimped into the connectors that are attached directly to the bottom of the fastrack. I read that having it as close as possible to the train is the best location. I tested the circuit breaker and it pops within about 2 seconds. I also learned quickly that the whistle switch on the ZW adds voltage and makes the train go faster. Luckily I had that circuit breaker as I made the train derail.
So the wiring goes as follows... ZW post A to circuit breaker, circuit breaker to power distribution block, power distribution block to track. ZW post U to power distribution block, power distribution block to track.
So my questions are...
1) is there anything I am missing in this basic setup?
2) are there any dangers I should be aware of having my two year old son with me running the trains?
