Machynlleth to Pwllheli 1988, Large Logo 37s on Mk1s, Ice Cream Van 150/1s Still Semaphore Signals. Or shift forward one year identical rolling stock and RETB Signallng for something different... Great Scenery, Great Trains and some fantastic structures en route such as Barmouth Bridge. Only the Sprinter would have to be built from New and could be layered onto other suitable DLC.
Great Idea with add ons longer term.....ie Aberwystwyth.... to Shrewsbury. Class 24 and 25’s included.
