Adding a Narrow Gauge railway to TSW would be very unique. People would love the Ffestiniog as it includes engines from around the world, and it’s quite a scenic and nice route.
Steam is on an indefinite hiatus unfortunately so steam routes are out of the question. Although, I wouldn't say no to the Tallyln Railway.
Technically they could do FR/WHR with their diesels, but that’s not going to sell many copies compared to having a Garratt or Double Fairlie.
Would definitely love the Tallylyn. But not with the current state of steam. If it ever does get fixed to a reasonable level, this would be an excellent choice.
