My trip to Georgia in October 2010 didn't end with a lackluster ride on Amtrak. Here in Part 2 we will examine some notable points of interest in the Athens, GA area located along the CSX Abbeville Sub, which is the former
Seaboard Air Line route between Wilmington, NC and Atlanta, GA. This line is cleared for double stacks and also sees a significant amount of Autorack traffic so there are usually a good number of freight trains hanging around and to put a cherry on top the line was re-signaled in the 1980's with classic US&S colour light signaling.
Today's trip will focus on three main areas. The first is the diamond crossing between the Abbeville Sub and the former
Central of Georgia branch to Lima. Second is the MP 511 intermediate signal that I have featured in the past and third are the MP 515 and 517 intermediate signals that I went on a little road trip to document.
You can locate the
entire set of photos right here.
I'll kick things off with a video taken at the MP 511 automatic showing a short doublestack container train heading north on the Abbeville Sub lead by ES44AC #759 and C40-8W #7873.
Here we watch as a southbound doublestack train pounds the insulated rail joint at the 511 automatic. That train was lead by
C40-8W #7715.
Next we move downtown where we see CSX GP38-2 #2768 sitting across from the old Athens Station on an industrial siding.
The old station building itself is pretty impressive and today is used as a CSX maintenance and crew base.
The
crossing with the CofG is non-interlocked, relying on
electrically locked derails on the former CofG line and
Rule 293 "Stop and Check" signals on the Abbeville Sub. Beyond the crossing is a
long viaduct over Sandy Creek.
A signal equipped with a (
C) plate
means that when displaying an all red indication, Rule 293, Stop and
Check, applies instead of Rule 292 Stop or Rule 291 Stop and Proceed.
Trains making a stop and check must...stop and....check that the derails
or movable bridges the signal is attached to are in their properly
locked position. In this case if the derails on the CofG line are in
the proper place it is safe to proceed over the crossing at Restricted
speed. Here we see the southbound mast signal equipped with the
appropriate
(C) plate.
The SAL/CofG diamond has since been fitted with flange riding crossings to eliminate the maintenance intensive and speed reducing flangeway gaps on the
main line. Similar to the Darby Rt 11 crossing this shows you do not need a sharp angle to make flange riding diamonds work.
One good thing about the crossing was that unlike the other
interlockings and block signals, these were not approach lit.
Unfortunately that also meant that just because traffic was flipped and
one of the signals displayed a Clear indication a train was not
necessarily approaching.
The Abbeville Sub is easy to railfan because a good deal of it parallels the Atlanta Highway so it was not hard to find and photograph the intermediate block signals such as this one at
Milepost 518. Here you can see the
US&S style N cast iron integrated color light units which were dropped from production for their current line of modular stack signals. This intermediate signal is also the southbound distant for the siding at HARPER.
At the Milepost 515 intermediate I was quite fortunate to have the southbound signal light up indicate an approaching train.
This turned out to be a mixed freight with another C40-8W #7809 and followed by C40-8
#7571 and SD40-2 #8020
