O31 track is an excellent choice. It's cheap and plentiful. Although Fastrack looks good, it's expensive, noisy, and can't be cut to special lengths without special surgery. Plus Fastrack switches are cheesy and major expensive compared to the old reliable O22 switches for O31 track. An LW transformer is a step up from a 1033. It's an excellent choice because it is powerful and economical without spending KW or ZW money.
