Today I have fiddled with lots of different things. I found some DC to DC voltage reducers which would feed my LED lights nicely, so I decided to have a little play. I stuck two copper tracks down where three houses are going to be placed and soldered some LED's to those tracks.

The extra wires are for a yellow led that light up the hallway. The red and black wires go under the baseboard and power the lamp posts also with copper tracks.

And this is the magic little DC to Dc board :

Attached to a USB lead thats connected to a usb power hub this reduces the 5V to 3V and will power something like 50 LEDs.
Rather than using resisters or putting LEDs in series this seemed an elegant solution. I had the reducers anyway and I can use them for anything really, I think Max input is 30v and the output is what you set it to. I like the result anyways.

Next I decided to work on the tunnel exit. My spouse found some railway bits at a car boot sale this weekend and it had some tunnel entrances included. Supported by crumpled newspaper I laid some plaster bandage down and fabricated this:

The idea is that the station is going to sit on top of this in the corner. Sitting on a piece of plywood that will be removable so derailments can be easily sorted. I've started glueing some bits of cardboard together to turn into a station platform. Rather than using ready made or shop bought stuff I want to try and make it myself so it would fit round the 2nd radius bend in that corner. Lastly I painted the Hornby R657 girder bridge grey and used the leftover paint from that try try and make something of the plaster underneath the track.
