Rail yard...newbie here

[Brakie]

Having ran a short line with 2 locomotives for 14 years I would really have liked to have a 2 stall locomotive shed.

Yes, but that's a real railroader talking about a real railroad. On a model the track really only serves as a place to store power. How much space should be dedicated to that is the question here.

A small lead,a switch and two tracks-not much room at all.

I don't see any reason not to have a small engine area.

BTW..last time I looked model railroading was modeling a railroad and in that light we should emulate the prototype.
