Hi, 1) I used to have a 4x8 HO layout in my basement in a small space but dissmantled it once I realized my c44-9w could not run with rolling stock behind it, it just kept derailing them on curves. So I'm wondering how large the radii must be in order to keep it running. My new layout is also a 4x8 but it can be expanded to about a 5x8 or a 6x8. (I have seen the rp-11 but dont really understand it) So my first question is what is the minimum radius size will I be able to run this? and 2) What would I have to do to be able to run multiple locomotives at the same time on the same track or one in a yard and the other on the main line without being too expensive if thats possible... and 3) Would 2 main lines seem too complicated, crowded, or unrealistic on a 4x8 layout. Thank you for any help you can provide to any of these questions
