It is 6 baseboards.
And is an IPortal, that can intake 10, one mile long, trainz consists in the receiving yard, sort them over 100 foot long -0.50 % hump, where they smoothly roll into the classification yard at a slow speed of 5 mph. Then the assembled consists can be pulled out into a departure yard that holds 10 one mile long trainz ready for dispatching out of the IPortal, to another one of my routes.
All together the route can handle 30, one mile long trainz consists, and hundereds of locos ... but the framerates woulds be awfull, with all those high poly cars and locos.
It has a 360 degree roundhouse, with 2 locomotive service tracks, with sanding, fueling, 2 locomotive ready tracks, 2 MOW crane car tracks, and caboose storage tracks.
Taking long, wide screenshots, is very difficult to post, as FOV is hard to capture.
