This is a really nice looking start to a route. I posted a photo of one the real CN G12s last year, re-trucked from standard to narrow gauge for use in Newfoundland, though they had really short careers and were mainly used for parts for other units. I haven't played with the shape file with the G12 in RWTools however you should be able to edit the wheel base to convert this to a narrow gauge unit if you really wanted to do a narrow gauge route. Newfoundland's railway actually had a small standard gauge terminal at the ferry dock where they received standard gauge cars from the mainland that were re-trucked for the island, meaning you could do the same thing with the standard gauge cars in RW Tools like the locomotives. Editing shapes 101 if you are interested, there is a section in each shape file called "SourceLToPTransform" and another section slightly lower called "TransformName" which reference which each line in the SourceLToPTransform is supposed to represent. Below is an example of that section in a tank car. With this particular car (if not all, they are setup the same) can be changed to a narrow gauge unit simply by editing the lines noted Bo01 to Bo02wh04 which are the bogies and wheel sets. This tutorial tells you had to edit the SourceLToPTransform section if you are interested.
https://railworksamerica.com/index.php/ ... t-position A modern narrow gauge route is completely doable in this sim as you can do the same with the track as well, editing the original shapes (making copies first of course) which can allow you to represent lighter and narrow gauge track as well such as 60lb to 100lb, it just takes a basic understanding of these files and some practice. If you do clone and make your own narrow gauge track you can use RWTools to replace the track you have laid thus far in a matter a few clicks saving any work you have done to date. If you wanted to do the modern isolated equivalent not far from Newfoundland which only has a 7 mile mainline and transports some 4,500 cars a year carried by a CN railar ferry, take a look at this video done by the railroad itself.

https://sopor.ca/en/ which was only built in 1976 and most don't know exists even in the railfan world. It is a modern contradiction and railway marvel in it's own, built at a time when most similar lines were being abandoned and very successful from what you will see. Food for thought.
