Definitely Enola!

@@BillSCHRUM Thanks!

As per Ron: With regard to the question about brass stock. In my talk I was talking about various shapes of brass stock, for instance angle, and channel stock. These are made by Albion Alloys a British company. I purchased mine from a Canadian company called flexi-i-file flex-i-file.com/products/brass-angle-90. (flex-i-file.com/products/brass-angle-90) The material is expensive, sizes are metric and the lengths are only a foot, not like Special Shapes where you could purchase 3 foot lengths. As far as H column material I would seriously look at Model Memories, I know they have pre-made catenry poles but they might also sell just H column material.

@@PhiladelphiaChapterPRRTHS okay thanks

Happy to explain... PRR typically did not use traditional catenary structures in tunnels. The tunnels pre-dated electrification and there wasn't sufficient clearance above the trains when catenary was installed in the 1930s. Instead, PRR typically anchored closely spaced, short, insulated hangers to the tunnel ceiling. Attached to them was catenary made of a messenger wire on top and a contact wire on the bottom clipped close together with no sag like traditional catenary. I did something similar with one contact wire instead of two inside the tunnels. To support cross pieces at a constant height, I glued pieces of 1" x 2" clear pine to the sub-roadbed on either side of the track(s), on end, every six to eight inches. The blocks have a 1/8' slot in the top. I cemented 1/8" x 1/8' square brass tubing into the slots. Centered over the track, I made and soldered 0.020" diameter phosphor bronze wire catenary hangers - the type shaped like a "V" with a "tail" on the bottom. To the underside of the tails, I soldered a 0.020" phosphor bronze contact wire. I tested pantograph contact with different types of engines, tweaking the position of the contact wire as required. A tunnel lining hides the pine blocks. A removable tunnel roof supports the scenery, but allows easy access to remove derailments and make repairs. Tim

​@@TimGarner-tv2ok I see! I also scratched build ho scale prr catenary bridges with transmission towers exactly like in prototype photos or in real life of my own. I ordered some ho scale prr catenaries either from Shapeways Steven Smith design of making catenaries Shapeways company produceor model memories which Don produces of making pieces of catenaries. Those mast end transmission towers that u scratched build urself that be front of Union Tunnel where transmission towers end at tunnel of power lines go through white tube under ground of city didn't want transmission towers run on top which train runs through tunnel I heard I myself will be making those exact transmission towers poles that be front end of Union tunnel in future. Many years I used to live in city close to Broadway street of prr/Amtrak northeast corridor mainline in that area but move out of city now which I ride with my dad or aunts seeing those those mast end transmission towers end at Union tunnel of something like that I want make scratched those things at time when I was kid but as grown man now which in future I will make those exact stuff too there. Thank you for explaining it to me how you went about putting in catenary overhead support contact wire with wood blocks before actually make Union tunnel leads to Penn Station soundbound. I also do custom scratched build model railroading making ho scale prr style catenaries with transmission towers. Anyway keep up good work and wish you best of ur layout being completed when it's all set and done there!

​​@@TimGarner-tv2okNice! And other question the 2 transmission towers masts real close together of power transmission towers mast ends by union Portal tunnel which power lines electricfy underground due city didn't want transmission towers above ground in neighborhoods while train runs through tunnel what materials you use to make that incredibly special transmission towers mast that end power lines by union Portal tunnel along with what materials to get of making those exact 2 transmission towers very close together where power lines ends at Portal tunnel of going underground? Reason why I ask is I'm planning on making those exact transmission towers masts where power lines ends too. Is there a link maybe you can send me of how exactly make those structural support pieces that holds for 2 transmission towers in place where power lines ends by union Portal tunnel that would be great!

Special Shapes made the brass H beams and L-shaped strips. Unfortunately another company acquired the company a few years ago and stopped making these brass shapes. Model Memories makes H towers using another method.

​@@TimothyGarner-w6l What was cause of reason special shapes went out of business there? With 1/8 h Column Brass length of 3' you can have luxury get whole lot of them. But now with that company gone the limit is only a foot which u can barely find those anymore which is difficult. I'll start sticking with getting many more from model memories there. And thanks! Keep us updated how you making progress on your prr catenary layout in Baltimore City area there! Wish u success on that layout.

Glad you enjoyed it! Thanks for sharing.

Glad you enjoyed it! Also, many thanks to Frank Tatnall for presenting and allowing us to share through this YT video.

The video description looks correct. Is this spoken in the video?

Glad you like them! Sharing as many as allowed.

Agree. Lots of PRR and northeast rail-fans looking forward to it.

Agree, its definitely going to happen and sooner than later.

Yes, not sure what the PTC plan is for 1361, if at all. Depends on where it may be running.

Agree. We understand that the plan is to have vintage equipment behind the engine. Looking forward to seeing what develops.

Thanks for sharing. Great memories.

Wonderful! Good news coming from the museum, we're all looking forward to seeing 1361 in action again. How far along are you with the live steam build? Maybe you could present over Zoom at one of our future meetings?

Glad you enjoyed it

As per Tim Garner: Within the tunnel, the side walls are made of 1/4" MDF glued to the sub-roadbed. Every few inches, there are 1/8" deep slots to hold 1/8" wide brass tubing across the tracks. The contact wire is soldered to the underside of the brass tubing over each track. I test each soldered connection for alignment and smoothness to prevent pantographs from snagging and adjust, file, and sand as appropriate.

Thank you. Tim is a great modeler. Hope we can share more on his progress in a future presentation or High Line.

Agree. PRR was an incredible operation in its day!

Thank you kindly!
