Walthers Single Track Railroad Arched Pratt Truss Bridge HO Scale . Layout Part 8

In this video I build the Walther Single-Track Railroad Arched Pratt Truss Bridge in HO scale, kit # 933-4521. This video is part 1 where I build the model and describe my experience. There are some parts of the construction to be aware of to avoid mistakes, but the fit is good with little flashing. Part 2 will come later to cover painting and weathering.

I love these old RR bridges. I have followed a line in my area over the years and taken many photos. One in Sunny Valley, Oregon, I measured out by hand, it spaned a deep gorge about 100 feet below...glad i didnt meet any trains that day. Your model looks great!

[@SPSteve]

Nothing better than watching a train cross a vintage truss bridge. I had to have a couple on my layout. Thanks, and I'm glad you didn't fall getting data.

[@derekalexander4030]

Nice tutorial on the bridge. Thanks for pointing out the possible build problems. You probably saved some modelers a headache or two when they build it. Thanks.

[@bncsystemsshortline]

Nice build and you did find out how easy it was splicing the 2 Bridge tracks together.

[@SPSteve]

Thanks. I did the track splicing and it worked out well. Not too difficult.

I've just finished building one of these kits. at 3:30, what looks like a misaligned bottom gusset is actually a result of the asymmetrical side bracing at that point. The two center nodes are symmetrical, so it's best to start there. These parts are the correct length so there's no need to leave a gap in the middle. All my X bracing fitted into the holes perfectly, as also with the double track version I assembled about a year ago.

[@SPSteve]

thanks for the input. I'm don't know much about these bridges so I rely completely on the instructions. If the instructions are unclear to me then I'm just guessing. I don't remember why it didn't align; I must have installed something incorrectly. In the end I think it'll be serviceable, if not perfect.

I need a dry wash and a bridge over sand. But my layout is operations based so it is just plywood with no real plan for verticals scenery changes

[@IMRROcom]

@@SPSteve On the car front, just gut done fighting a Snap ring that holds the magnet in place for a the A/C clutch on our van. They need to make a rule that if you can not install or remove a part after the engine assembly is placed into the car, that engineer needs to be shot in the knee, twice. Sure if the engine is out of the car, it would be an easy Job. On the other hand you need to remove half the accessory system to get to a part...Sucks

[@WWE_actionfigure-matches]

can you use non bridge track on the bridge

[@SPSteve]

Sure can. I used bridge track on my bridges, but you don't have to.

[@Tom-xe9iq]

Have you built a Central Valley bridge kit? How did they compare?

[@SPSteve]

Tom, I have not built a Central Valley kit. I had a couple of their 200' double track truss bridge kits but simplified my track plan and no longer needed them. I would say the Walthers bridge is much simpler to build than the 200' Central Valley kit.

[@josephkubala4795]

The Central Valley bridges are much more complex. First, you have to assemble the girders, then cut each one to a specific length and angle based on the templates in the instructions. Using the provided template is absolutely imperative. Bridge ties are included that require rails (code 83 & 70) to be installed. As stated in the instructions, it is a 30 hour process. One good thing is that CV includes bridge length sheet metal stiffeners to provide excellent support. @@SPSteve

Walthers has changed the bridge track and it now comes in a single 36” piece. It’s now under the Walthers brand and not Shinohra. It’s also a different part number

[@SPSteve]

Good to know. Perfect for these bridges.

[@IMRROcom]

By the way, You are building a kit. it would not hurt to add the part number of the kit to the end tittle, that way when people are looking for a how to on that kit, it will show up.
