Tyler, Chuck (PRR1950) gave excellent advice. If you aren't sure what operation you want, then maybe see if you can find some home layouts in your area to visit, or setup something simple on the floor to try some different types of operation before committing to a lot of work and expense. I learned that I do not like switching a lot of industries by visiting a large home layout and participating. I also learned this from an S-scale club in Pittsburgh that sets up two layouts at every Greenberg show. One is a point to point switching layout, and the other is an American Flyer over and under double loop with operating accessories for the kids. I like the scale modeling on the switching layout, but like the movement round and round with the AF layout. So my layout will be similar to the AF layout, but with scale modeling.
