The Ffestiniog Railway (FR) and the Welsh Highland Railway (WHR) are both laid to the 1'11.5" (597mm) gauge, and share Porthmadog Harbour Station and other facilities, but they also have some major differences. One difference, which I noticed at Porthmadog Harbour Station, is that WHR rolling stock is built to a much taller and wider loading gauge than FR stock. FR "Hudson toastrack" open-sided coach No. 38 could run on the WHR, but WHR "service car" (toilet/buffet/brake van) No. 2010 would not be able to run on most of the FR.
