Circleville Interlocking

Hello all:

I've been reading with great interest the thread on the interlocking model
board from Circleville, Ohio on the Columbus District.

It's important to realize (as most have) that this interlocking (and area
as a whole) went through several iterations over the decades. The photo
Matt presented appears to have been one of the last steam era arrangements.

Of interest was the Spring Switch and bracket post signals at the west end
of the center sidings at Dorney. This would be to the right of the board
photo. The N&W had several center sidings along this route to allow loaded
coal trains to duck out of the way of faster freights. It appears
Circleville Tower had control of the west end of Dorney.

I've attached (I hope) the PRR interlocking diagram of this area circa
1967. It's a bit cleaner than the old model board and shows what updates
were made by this time.

By best,

Eric from Ashville
Columbus District
