This is looking good! I hereby emit a "gimme"!

Your dock & ship tweaks are interesting and a good move to more prototypical or realistic conditions. Perhaps I will do a copy-cat for the 50-60s BR version of the route. A better driveable ferry than the big ship currently used in D&D would be one improvement but I can't find one on the DLS.
Dearnby & District is building up a head of steam in the virtual works of various route & session authors. A revised Version 2 route will be uploaded before too long, configured for session builders using Enhanced Interlocking Towers (EIT) but otherwise unchanged from Neville's first upload of Version 2. Two EIT session authors have been collaborating with me (as the revised route tweaker) to produce EIT sessions, one of which will be uploaded at about the same time as the revised route. The route and this session will be for TANE SP4 but also work in TRS19.
The second session is made just for TRS19 and will come a bit later, when the author perfects it.
The revised route, though, can also be used to make older-fashioned non-EIT sessions, should anyone wish to do so. The route itself will be free of any embedded locos or rolling stock except for a very few scenic items. The portals will also be unpopulated in the route so that session builders have a blank canvas, so to speak.
When this revised route and first EIT session are uploaded, a post will be made in the Freeware forum section with some notes about them.

In time there is to be a Version 3 of Dearnby & District; and further versions, each of which will have extensions. I can tell you that Neville's very high standards and artistry in making these extensions is being applied! Upgrade your GPUs now!

Dearnby & District proliferates, then. It's good to see it do so, especially via various collaborations and re-uses. Perhaps there are others who might like to make contributions? Neville and me have always wanted an expert in Trainz industry stuff to help with making some well-organised railway deliveries beyond the coal and mail services in the current D&D........... For TRS19, people knowledgeable about PBR textures and the Turfy stuff would be a great boon........... Any volunteers?
