This spur appears to have been constructed in the 1960s, around the same time as
the nearly adjacent Columbia Branch (which is shown on the next page of this tour).
The Waterloo Branch is minimally active and primarily serves the Maryland Wholesale
Food Center near the intersection of US 1 and MD 175.
This is the first of several significant branches encountered as we head westbound
(south) on the Washington Branch. It is omitted from all editions of the ADC maps
that I've seen.
Please note that the Topographic Maps linked below date from
around 1980. Many of the roads and intersections, particularly those near
Columbia, have changed since that time.
The only significant grade crossing for this spur is here at Dorsey
Run Road. The road bridge a short distance away spans the Dorsey Run
tributary of the Little Patuxent River. The spur basically parallels
the tributary along its northeastern bank.

on the line during April 2018.
There are no interesting stone arched bridges along the modern spur, just
plain, boring piped culverts. I've included this one simply to show the
unique design. It can be found just west of the grade crossing.
By its rusty condition and that of the rails, this modern bumper post,
a "Hayes Type WD", would appear to not see much use, however this siding
did have a few cars sitting on it. This bumper was later replaced with
an Atlantic Track model AN3.
Other sidings split off the spur as well. This view looks back toward
Dorsey Run Road.
Here's the view with the bumper post at my back. I neglected to note
the name of the warehouse, but by the cars on the siding it does appear to
actively use the railroad for shipping.
Reader Dean Cogar sent the following update:
"Here is an update for the web page-I work for Sysco Foods-Baltimore and
enjoy the daily passing of freight trains past our facility at
Dorsey Run Road, and, up until about 4 months ago, we would receive about 2 to
3 box cars of frozen foods per week. But unfortunetly the early delivery of
these boxcars 1 to 2 days before scheduled, and the railroad's insistence
that we pay delay charges while they sat on the siding till there scheduled
delivery time caused Sysco to end rail use for deliveries. It was with
sadness as I watched construction workers take a torch to the rails to remove
them for a warehouse expansion that is currently under construction."
Ballast paths reveal the end of the spur had previously split even more
directions. At the time of the photo this warehouse had limited activity,
and one adjacent appeared shuttered. A distant trackside sign reads,
"Track Out of Order Do Not Use".
This railcar near the end of the line tells us deliveries via train were
still happening in 2021.
ARMN is a reporting mark employed by Union Pacific (UP) on some of its
refrigerator cars. UP acquired the mark as part of its merger with the
Missouri Pacific, who about 1973 had applied ARMN to cars it had acquired
from the American Refrigerator Transit Company.
