I laid the B&W rail maps from Going Home on the combined campaign maps from the box set.
The Poland rail map was relatively straightforward, as if it was drawn right from the source material. Although the scale is slightly off, should be more like 50km instead of 60km.
The Germany rail map was maddening, as cities and coastline weren’t lining up. I belatedly realized the map needed to be rotated slightly. It looks as if the artist didn’t have access to the color Germany map during production.
The lack of compatibility between the maps disturbs my inner peace.
EDIT 5/12/2019 A great alternative is Wikimapia, a nice balance of detail, without being overcluttered. Take a look at these coordinates. The black lines are the railroad, and the yellow are highways. And then you can see how I took a screenshot and adapted it for play here.
