Staging Entrance-Exit Track Rework Doswell Branch

As mentioned in previous blog posts, the tracks that enter the upper staging yard on both sides (North End and Doswell Branch) have curves that are too sharp.

The track plan originally had 30" curves in these sections but during build the curves were installed much sharper due to trying to fit the track to the physical space that was in place.

After the first op session ran, it was discovered that the curves were causing tracking problems with long (85') cars. Primarily, these are passenger cars, the Amfleets (new production Walthers Proto) and Superliners (a mix of Kato, Walthers and Walthers Proto). As there are something like 10 or 12 Amtrak trains on the full operations schedule, we needed to rework these areas to solve the problem and make entering or exiting the staging area perfect.

The Doswell branch side was tackled first as it was only going to impact the track into staging. After a survey was performed (lots of measuring, test fitting and game planning), the area was torn down to benchwork and new subroadbed up was installed.

After the rework, a 37" radius curve is now used and there were two industrial spots added to give the staging/Doswell crew more operational interest.

The walkway into the staging room was also enlarged so this effort was a ringing success all the way around.

All finished!
