... the available space, and a scanned track plan imported into a picture shape which clearly won't fit that space as it stands: 2_191552_340000003.png The actual position of the picture shape is immaterial, because we are going to curve it and align it over the control template. On older systems there's time to make a quick cup of tea while Templot does its stuff, and here's the result: 2_191552_300000001.png You can see that I set the curving offset to match the up running line, and the scaling and curving has matched very well: 2_191552_260000000.png Of course, it won't be possible to copy the curved track plan exactly. A prototypical curved goods shed is going to be very hard to find. The tracks would have to be adjusted to allow a straight run through the shed: 2_191552_380000004.png But as a "get you started" background guide this looks a promising method. The control template can be set up to any desired alignment to create the curving line. In practice this example is perhaps a bit extreme, and a more gently curving line would be more practical ...
