Nice work on that station.
I'm currently working on a "Welsh Narrow Gauge" pack of various items that you may be interested in if you are planning on making an accurate Ffestiniog route.
Currently got track for 1ft 11in gauge (Ffestiniog, and some others use it) in clean, rusty, snow and snow/rusty versions. I might make some for the other gauges too. I'm right at this minute working on some dry stone embankments, and once their done I'm going to be doing a few bridges and tunnels. I also plan to make a few station buildings too - based of the Ffestiniog ones, but designed to be "modular" so you can build your own stations with them. I'm also on the verge of making some ground textures, cliffs, waterfalls and rivers suited for Snowdonia, but am not entirely sure whether there would be much interest.
What exactly is in the pack isn't for certain yet, as I want to use it to make my Christmas Route, so it will solely depend on how much I can get done within the next week/week and a half (to give me another week to actually make the route).
I'm currently working on it all day, everyday so it will almost definitely have all the track/bridges/tunnels done by then. Whatever isn't done by then, will be put in a second pack for release after Christmas. My eventual aim is to have a pack I can use for a large ficticious (but based on existing lines) Welsh route, with several narrow guage routes, linked by a mainline route (ala Blaenau Ffestiniog).
Due to the amount of time I've spent on it, I'll probably be releasing it as payware though. I'd like to do it all for free, but when I'm making Trainz items, I'm not working on my php projects. Depending on how much I do, I may release some of the basic items (track for example) as freeware, and do the rest as payware.
