Drawing of an old-fashioned railway speed sign found in Wales

Was in Wales last week. On a journey along a very old railway line, I saw these metal speed limit signs that were mounted back-to-back with each other (presumably so that trains coming in both directions can see).

To be honest I can see why they don’t use them anymore, because you can’t read the numbers for shit. However, I thought I must be able to use them in some cool graphicdesign™ at some point. Leaving this here as a reminder.
