As you can see, I have fitted the previous board to the new one. There is a discrepancy of height between them. The new addition is set higher than the main board as there will be two levels on the track and by starting in the middle, I can make the resulting grades less than if I had everything starting at the lower level. The existing off scene staging is a board 3' x 8". This will be added along the front of the main board. This will give me a proper end to end option rather than an out-and-back style.

The perspective from the wide angle makes the main board look only as large as the terminus board. In fact it is 6' x 2' 6" whilst the terminus board is 5' x 1' 6".
