33" is used in most cases, 36" is passenger cars and specialty and larger freight cars, there are also some other wheel sizes for some unusual freight cars.

I got out my calculator and the difference is 3". 

I use Reboxx wheels or NWSL wheels. I measure the wheel length with a dial caliper and order the appropriate wheels. I use the Micro Mark truck tuner to make slight adjustments to the plastic truck.

Kadee wheels are Sintered Metal that can accumulate dirt. Do a Google search for Sintered Metal.
Use machined wheels that are solid metal. They will be a nice shiny finish unless they are weatherd.
