These by far take the most time as I have to cut out each individual letter. I could probably complete ten of the ones above in the time it takes to do one of these. If you get too cocky and try to soak more than one letter at a time in water, it inevitably ends up ruining the decal.
When you fail, try, try again. Back to signals. I managed to light the first signal tonight on the layout! Say what?
I installed a small dwarf type signal outbound at Ottawa Yard. It displays yellow and red only.
