This shows 2 sidings and the 2 main lines lead to the other side of the room via a lifting  access.  The single track leads down to the harbour.

This crossover allows me to change the route from the outside to the inside track.

Unfortunately the incline was too steep so I had to change everything, cutting 4 cm off to make it lower, so now the backtracks go down 2.5 cm over a length of 275 cm. The front tracks go up 4 cm over 244 cm making it a gentler climb than earlier which is necessary for 8 coaches with lights.  The earlier version was ok for all the other trains I have without lights.

I have started building the frame for level 3 and have nearly finished the baseboard for one train going up and another going down in different directions.

The previous incline was too steep for the Pullman coaches with lights so I changed it to be less steep because last time it did not work.  Now it can climb with 8 coaches with lights.  Each coach is one foot and the train is also a foot long, in total 9 feet.
