New Photo Of Rock Creek Trestle

Georgetown Branch related links, History, News, Prototype

As you all know, the Rock Creek trestle was torn down last Winter/Spring. I was able to take some photos before the final blow was struck and thankfully captured some crucial images of the structure. Unfortunately I wasn’t able to take measurements, as the deck had closed before I had a chance to get up there, although a crane operator mentioned that the girder bridge section was slated to be preserved, as it was deemed historic. (dates back to early 1900s)

Montgomery County Parks Dep’t. posted this on Twitter today:

Site of the B&O Rock Creek trestle.

The view is from the hiker-biker path and is facing to the North. To the left, you can see the old abutment built by the B&O in 1972, which held the rebuilt section of the trestle. (steel) In the foreground, if you look very closely, you will see the old wooden pilings, cut down and about to be entombed in concrete. Here is a photo I took about one year ago today:

I am currently in the process of building a model of this trestle. More updates soon.

Jan 21, 2019: Layout Update (Only One Year Late)

Model RR, News

Yep. This video was shot just over a year ago. Why am I posting it? Because it’s been eating me up and I decided enough was enough. Sometimes seemingly simple goals become unrealistic whether because they were set too high or other things got in the way. In this case, it’s a bit of everything. The transmission repair project took over last Spring and dominated my spare time through the Fall. HPDE season prep and subsequent packing up/cleanup took the rest of the Fall away. I was burned out and it took a while to get back into the swing of things.

So, enjoy this video. There’s actually a good bit of track work and layout progress that is NOT depicted in this video, so I need to do a new one! I will work on cleaning up the layout room and getting a new video done. In the meantime, enjoy this. Post any questions/comments below.

One final note, this video was done without any real production. I just wanted to “get it done.” Forgive the lack of quality and I hope to do better in the future. I would also like to do some features on the side projects I’m working on like building the Bethesda station and the Rock Creek trestle. Lots going on!

Georgetown Flooding Image and Video

News

This postcard view of Georgetown, likely from 1942, shows some of the extensive flooding along the waterfront

This neat image popped up on eBay recently. I believe it’s from the 1942 flood, one of the worst.

At the same time, while searching for more info on flooding, I stumbled across some stock video footage that shows 1936 Georgetown for a brief moment. Photos of the branch are rare; video doubly so. The Georgetown section begins at about the 56-second mark.

Rock Creek Trestle Construction

Georgetown Branch related links, History, News, Prototype

The Purple Line folks have shared a couple images on Facebook. The shots were taken atop the old B&O abutments to the trestle across Rock Creek. The new right of way is about 15′ lower than the original RoW. They “shaved” the top down. (the new bridges will be much lower than the original one.) https://www.facebook.com/marylandpurpleline/

Cool Modern Aerial Shot of Bethesda

News, Prototype

The Montgomery County Council posted a neat photo to Twitter which shows the construction going on in downtown Bethesda. Of interest is the lower half of the image which shows the old Georgetown Branch right of way. On the right is the Air Rights building, which straddles the tracks. Next to it is Wisconsin Ave, where you can see the bridge crossing the tracks. (it is the concrete section.) The cribbing you see is approximately where the right of way exited the Wisconsin Ave underpass and continued on to the South. The line curved down toward the bottom of the photo. Just above the right of way you can see where old sidings branched off from the main track near where the concrete parking lot is. Pretty spiffy!

Progress on the Rock Creek Trestle Design

History, Model RR, News, Prototype

I’ve been working on putting together scale drawings of the Rock Creek trestle on the Georgetown Branch for several months now in my free time. I’m getting very close to have a final working set of plans that I can use to build my HO scale model of the bridge and wanted to share a quick screen shot to see what it looks like.

Bent #10, which supports the east end of the deck girder bridge.

This is very much a work in progress and the drawing reflects that. There have been many challenges with this project. Some of the big ones include the lack of images of the trestle from the time frame that I model; 1945-55. Another includes the various versions this trestle had throughout its life. It was originally built in the late 18th century, rebuilt some time in the 1920s, and again at some point in the 1950s. In the 60s it burned, in the 70s half of it collapsed. It was rebuilt, burned again in the 1980s rebuilt in the 2000s, reopened for pedestrians and finally in 2019 it was demolished. I took as many photos of it as I could (found in the Gallery on the main site) but due to the many modern additions, it’s nearly impossible to determine what was original and what was new.

I am doing my best. There is a lot of staring at photos for a very long time, trying to determine where bracing was placed, what height it was located at and what angle is correct. I’ve got about 3 photos that date back to the 40s and 50s. None are particularly good. I have a rough plan of the structure made by the B&O but it is missing many, many measurements. It’s a good starting place, and will give me a “good enough” on many measurements, but I wish I had taken more when the structure was still open to pedestrian traffic. Oh well. More to come, soon.

Talbot Ave Bridge Is No More

Talbot Ave bridge removal.
July 13, 2019: The current state of affairs at Georgetown Jct.

I was down at the Scout Shop in Bethesda getting couple last-minute items with my Son for his trip to camp tomorrow when I figured I would drop by the Junction and see the carnage. Wow. I was heartbroken to see it in person. The beheaded bridge piers and demolished abutment made for a grim sight. The Talbot Ave bridge stood sentinel for over 100 years and had become a cultural and social icon to locals. It was really tough to see the altered landscape. All around us it’s happening. I noticed as I drove through historic Kensington that the industrial area near the station is being gutted and cleared out, no doubt for some new shitty condo or office complex. It’s sad to see it all go, but that’s MoCo for you. Visit it all while you can, for tomorrow it may not be there.

Here is a link to my photos from the trip today.

July 5th Talbot Ave Bridge Demolition Photos

History, News, Prototype
Bridge demolition is nearly done.
The crane is positioned and ready to lift the bridge out of its home for the last 101 years.

Good friend Greg C. stopped by the Talbot Ave site yesterday to see what was going on. Well, the bridge was being hooked up to the crane for removal and wow, the site looks different. It’s a bit heart wrenching to see this landmark being removed, but nice to know it’s not being sliced up and destroyed altogether. Unfortunately the actual removal was not captured (it likely happened later in the day) but this will give you a very good idea of what the scene looked like.

You can view the photos here in my Gallery.

Talbot Ave Bridge Update

History, News, Prototype

I expect there will be more of these, but in the interest of keeping everyone informed, Greg forwarded an email this morning with updates on the status of the historic Bridge:

From: talbot-avenue-bridge-events@googlegroups.com

Subject: Talbot Avenue Bridge demolition begins

Today, a little after 7am, Talbot Avenue Bridge closed. By midday clamps had been attached to the girders and steel extensions, in preparation for later removal by crane. By the end of the day, the wood edging along either side of the Bridge had begun to be removed.

If you would like to view the demolition process, best viewing is on the 4th Avenue side of the Bridge (North Woodside).

The removal of the girders could happen soon, i.e within the next week and as soon as the end of this week. Purple Line continues, however, to wait for flaggers from CSX, without which this aspect of the demolition cannot proceed.
