Er, it's always been there, even from the first version of the list.
There's now some lovely piccies online in the
http://www.xpns.co.uk/tycoon/ directory. Most of them are TS screenshots that will be used as a basis for creating the livery concepts, though there are a few in there (and will be many more) with a suffix -F that represent the actual livery concepts.
Moving on, I also have a sample of the datasheets that may be used for something at some point.
http://www.xpns.co.uk/tycoon/370.png (these will eventually become HTML format docs) - due to not having a copy of the specs to hand (read: no Net connection for a while), that part is missing. There will eventually be a key to this info, but on the livery concepts, the off-black colour represents black, the off-white represents white, and magic pink represents the player colour. Note that those diagrams are concept images only. I'll probably need a little help with the final graphics.
