Thank you so much for your prompt responses

Is it possible to buy the car barn alone?

Hi everyone, I am just starting in the rail modeling world, recently bought the Lafayette train set and received it today. The thing is that I'm also planning on building a city scenario and would like to include a trolley car. I found the "Main Street" set but I would like to know how does the reversing track work, what is its diference with the regular track? and lastly I noticed you can buy the tracks in this site , would that enable me to build a custom trolley set or I still have to buy the ready made set?
Thanks for any help and sorry for making thisd so long.
