I think I'm missing something. Surely, to create the illusion that the train enters loaded and exits empty both entry and exit have to be on the same level.

The loaded train drops to the lower level to hide the loaded wagons.
The empty train climbs from the hidden lower section to the higher level and exits with empty wagons.

This means that the empty train has to climb that 5% grade at the same speed as the loaded wagon enters, stopping every two wagons as well. I know electronics can sort out the start/stop motion but 5% uphill with wagons (empty or otherwise) and starting and stopping to boot may just be a little ambitious. I use 1 in 30 ratio as a maximum. So for every 300mm along you go up or down 10mm.

If the empty train is one the exit level already then the distance between the crossover point is going to be about 150mm so that would be the total length that the loaded train has to drop enough to clear the empty train and the bridge support.

In theory it's a great idea but practically I'm not so sure.
