Just when we thought the engineering work was done, I discovered that the yard can have a runaround loop which only increases its capacity! Last night we began some major re-engineering.

1) Removed two switch at the yard entry and replaced with steady voltage wired switches. The switches are installed but not yet powered or tested.

2) Replaced the uncoupling track on the mainline with an uncoupling track/operating track combo. This will give flexibility in delivery points and permit use as a test track.

3) Re-installed manual switch for short engine siding in yard.

4) Installed bumpers at ends of spurs

5) Installed isolation pins where required except that the outer spur siding requires a block isolation pin.

6) Purchased a flex track operating section for the upper section. This will allow for a dump action from the upper level ramp to the lower level yard track.
