Jason,
Thats a lot more track than I thought you had. I like the fact you have connecting routes between levels. That is a throwback to my HO days, when most folks with multiple levels connected them. However, for those who like multiple unconnected levels, that is fine too. That saves on extra switches, and it is easy to run multiple trains. My motto is enjoy this hobby any way you like within the budget, time, and space constraints you are dealt.
