UKN_Downunder

I'm thinking code 55 in visual areas and 80 in hidden areas.

Thanks, thats all great food for thought to get me started. Unfortuntely the door opens inwards but it is hinged in a corner opening 90 degrees from a short wall to the adjacent long wall. I like the idea of a 4 track main line so maybe having a central through station would work well with adjoing terminating platforms. Assuming i avoid a duck under option would I be able to tun a 4 track main line 180 degrees in the space I have?

Looking for some help or suggestions. I now have a spare bedroom available to build a new N gauge uk outline layout. Recent purchases of 2 LNER Azumas Kato Class 800s have now got me wanting to get started. The room measures 11ft x 8ft with the door on a short wall. There are no wardrobes to worry about and the window is set high. For when the grandkids arrive, I would like to have a decent continuous run layout so I can let the Class 800s stretch their legs without them looking like a tailchaser and an additional track for commuter/freight traffic. I am thinking a main terminating station at one end a through station at the other end (thinking something similar to Wimbledon) with MTD and a commuter stop midway. Also if I could get a freight handling facility in that would be good but not a biggie as a hidden fiddle yard could hold complete made up rakes. So am I trying to get too much in? Any suggestions or inspirations. It will be DCC using Peco Streamline. What are recommended incline/declines to/from fiddle yard. Thanks.
