I have found that a 8ft x 4ft layout is most difficult to man handle due to both the size and weight of materials used in the construction.
If I was to start from scratch again, I would certainly design the same layout as at present but laid on a 2 off 4ft x 4ft boards and joined together, making it more manageable physically.
I have found in using a 8ft x 4ft board, that the maximum running stock to be one locomotive and three coaches or a three car DMU. On ending a session each time, the running stock is halted at the station, then run in reverse into a chosen siding by use of the points.

When designing a fiddle yard and station platform, a common fault made by beginners and that includes myself, is the length of rail to accomodate the number of coaches and wagons decided upon. A fiddle yard may have several roads laid, and each road having one or more RH/LH point interlocking to enable all roads to reach the main line.
A fault is to misjudge the required distance at points, is the total length of the number of coaches/wagons plus the locomotive will exceed the length of rail laid and will encroach the point and block other roads movement.
I ensure, when laying track utilising points, that the total length of rolling stock is measured and adding a further 6 inches (150mm).
