Documenting the Talbot Ave Bridge

As most of you will know, the bridge which crosses the B&O’s Metropolitan Branch and Georgetown Branch lead at Georgetown Junction is slated to be torn down. The sides of the bridge, which once belonged to a turntable, are to be saved and placed along a new stretch of the Capital Crescent Trail, which is nice. The bridge was constructed at some point around 1918 and has seen several refurbishments over the years. Much of the support structure rusted away over the years and as such the bridge has been condemned for the last year or two. Thankfully, it was recently re-opened to pedestrian traffic.

Photos from our visit are here in my Gallery.

Here I am on a chilly Sunday posing in front of the Talbot Ave. bridge. It snowed a bit while we were there. Note the giant logs laying on the ground; evidence of the brush and tree clearing the Purple Line folks are doing. Photo by Greg C.

Greg C. and I spent a morning at the bridge documenting it both with a measuring tape and with a camera. All in all, it was a very successful trip and I feel confident that I have enough data to accurately model the bridge in HO scale for my layout. Unfortunately, the model will have to be modified a bit to fit in my space, but I plan on being as accurate as I can. I think once complete, it will be a really neat model. Here are a few a sneak peeks at the drawing I am developing of the bridge structure:

Layout Update: 3/12/2019 – More Turnouts

The three turnouts in place for the track coming into Bethesda. Not the extra curved turnout on the right.

After building my first curved turnout a couple weeks ago I decided to build the next two to complete the track coming into Bethesda. I spent several hours over the weekend putting these together. When all three were done, I set them in place and realized I didn’t like how they worked. The first one was too tight of a radius. Hmmm… the only solution was to build one MORE turnout! This one a #10 LH with a 60″ OR and 46″ IR. It took me a few more hours to complete as I don’t have a FastTracks PointForm jig for a #10 turnout, only #8. So I used that and filed them down further to get the clearance I needed. Improvise. Adapt. Overcome… yeah.

Putting together the turnouts has been a tremendously rewarding experience and I take a lot of pride in how they turned out. I still have a bit of work to do with them, specifically I need to cut gaps, test continuity, fit them in place on the layout, paint, weather, install ties and wiring. Oh, and switch machines. *phew!* I’ll also need to modify the benchwork for the first siding which branches off at the start of the curve. This will be for the Griffith Consumers Co. coal & oil facility, which you can see here in this 1949 aerial view on NETR Historic Aerials. I will add a bit of a wing of plywood and Homasote subroadbed and then drop down for the coal unloading trestle. Ideally this facility will receive 2-3 40′ cars of fuel oil and coal. Here are some random LoC photos of the facility there. Unfortunately I don’t have a great shot of the trestle.
