Hello ShadowRock:
When I received no reply from you on this forum and the Trainz forum post re: "Last People to Actually Play Multiplayer" thread, I took the liberty of uploading the session as is. I have a group that all own the Nidder route and we were getting antsy to run it in MP ! 
There are no changes made. I only posted w/o asking since you had no license inside the config, which usually means it's free to use or duplicate.
If you had, I would not have taken the liberty to upload the session. Apologies.
I'm thinking that a rebuild with rmm trees would allow both Jet engine users and TANE users to enjoy the session. All of his trees are in the Speedtree 6 format, and show no errors in TANE. I can do the tree replacement work, if you like, (I am mostly a route builder and scenery maker) and send you the CDP? You could then clone it and upload it? I only suggest this as it seems you are busy with other life things.
I do hope Auran makes the localisation changes soon as well.
It's a great selection of rolling stock and locos, but some seem to not want to accept loads? I think it was the EOS gondolas?
We had fun running the session in TANE, with me translating industry names for the group.
