Crosover install on the Birdwood Sub' Part two.

Continuing on from part one, the turnouts are finally installed and Tortoise switch machines fitted. A temporary Toggle switch is fitted to operate the switches until DCC control is installed. After the work train passes through the crossover, three SD40-2's bring their train up the Tarragindi cut off and cross over to climb the Helix.
