I've long made my own routes for use only on my PC by merging the routes of others then enhancing them. I'd like to attempt one for the DLS (TANE) as the quality of my efforts has improved after some years of practice. 
There are three routes I've already merged because the config file license text appears to give permission to use them at will, as long as we acknowledge the original author. These are:
Dearnby by Neville Hill
Dearne on Sea by Neville Hill
UKSomewhere by Darkdan.
The Dearne on Sea style serves as my inspiration (thank you Mr Hill) so the other merged routes will hopefully end up looking something-like: 1950s BR Western Region somewhere on a mythical coastline.
I have attempted contact via the message box of this forum but so far no reply.
There are two other routes I'd like to use:
Glen Foloy (to become an Exmoor-like part)
Riddich Isle (to become a branchline coastal part)
Although I have versions of these routes, they seem to have lost their original author name as mine has taken their place in the config file, presumably as I amended them locally on my PC. I can find no licence text either. The original routes no longer appear in a search of the DLS, I know not why.
Does anyone know who the authors are, so I can attempt contact and get permission to use? Or what the original licence said?
Any help or advice gratefully received.
