I whipped up this print pack for my upcoming train block party, so I thought I might as well release it to the public as it'll be available on the server anyways.
The signs are all railway-related, and are all for the engineer driving the train, not for civilians (so no rail-road crossing signs). They are all replicas of signals used in the Dutch railway network. And even though you probably don't understand even half of these signs (I didn't until I looked them up), they still make your railway look cool, complex and hard to understand.
The pack comes with a complete set of icons. These prints are made to be used on
Barnabas' road signs, but can be put onto any 2x2f print brick.

What you're getting, and also what the signs mean and what brick they were made for:

If anyone is curious what the dimensions of the rectangular road signs are, the image is 512x615, but should be compressed into a 512x512 area.
I am aware the yield brick prints don't line up perfectly, but that's something on Barnabas' end. I have to choose between making it look good on a 2x2f or on the yield sign, so I'm going to PM Barnabas and hope for the best.
