A few if's here but, 1) If the RL is not to be used as a storage yard and, 2) If you are using the Hornby HM7000 system as control and, 3) Just using the RL for locomotives, Would not the use of the Hornby Power Bank HM7070 with a small section of isolated track on the RL simplify this? If using the RL to turn around a complete rake and engine, then as long as it's not scenic (lights going out in carriages) then it would work also.
