yes

well searched a lot watch many videos. check lot and lots of models. there are many of them and still i have no idea which model to go with. to simplify almost 40 feet of track i have in my mind because of room size. so veterans members recommend me some models i will choose from the list. do remember almost 1 feet of upward track and one feet down ward track for the door side of the wall. so help me to choose. i prefer sound one. rest you have to tell me which type of track and engine etc etc.   

 i want train track on wall in center of roof and floor. and for room door side gradually up to avoid door and then after door gradually down till middle of roof and floor. try to upload pic butt failed , dont understand why even file size is only 50 kb. share your email if possible. will send you there.

i am thinking like two side of the wall straight in the middle and the door side of the wall gradually up for the door and after door gradually down. and then remaining two side straight in the center of the wall. is that possible. if possible which model is suitable for that and which type of engine i will go with. i will make plywood wall for rail track. hope you guys are understanding my points and come up with best model for my purpose. 

well room size is almost 15 X 15 Feet. So which scale gonna work in that area? What is the difference in between sound and non sound? are you talking about train sound during run on track or some thing else?
