Hi all! This is a small idea that I had quite recently as an item that could be found in a set that added playability to a Lego train set. It's less for show displays and more for a child's little Lego City oval of track in their room. There's no electricity, just a mechanism that'll hopefully make it feel like the operator is a signalman!
It's not based on any particular signal box, but the signal is very clearly an old British design. The box is cut in half to reveal the interior of the box and to provide access to the lever of the mechanism:
It's a very simple set-up, with the mechanism being the most complicated aspect to it.
Here's a (VERY) quick diagram of the mechanism:
I'd love to hear any comments or suggestions to improve this!
I might put it forward to Lego Ideas in the near future, maybe with a little train to go with it!
Many thanks,
Isaac
