How does one piece of railway sign look like it’s made of wood?
That’s the question that prompted researchers to investigate the function of the wood sign found on the front of the locomotive in a railway tunnel near London.
The wooden railway track on the rear of the carriage is made of birch, which is a hard wood that is usually hard to carve out of the stone surface.
It is, however, possible to carve the surface into a form that would allow for the cutting of small wood chips to be made.
These tiny bits of wood were then attached to the wooden railway tracks to make up the outline of the wooden train, and this was the basis for the wooden rail sign.
Using the same technique, the researchers could also create a similar wooden train sign on the same track as the railway sign and it would work the same way.
This would mean that the train can be clearly identified as being made of timber, and the railway tracks would also be clearly visible to those in the vicinity of the train station.
The researchers say the result is a very practical, practical train signalling system that would be able to be used by railroads throughout the world.
While this new technology has a long way to go before it can be used for signalling in a real railway, the team say it has already shown promise as a way to make signalling on the railways more accurate and reliable.
