Yes Virginia, there is a new version of the PRR Panhandle being planned. It's at least a year out, but I've been playing around with the proposed dimensions of the train room and have come up with the following. The red areas are access hatches or hand holes.
Vital Statistics & Decisions:
- Size & Shape: Folded dog bone – 39.5’ x 11’ with a 7.5’ x 11’ staging area – approximately 517 square feet. Total size: 47' x 11'. This layout is nearly 3x the size of the previous version. We are considering a layout height of 48"-50”.
- Track: Mostly GarGraves with some Curtis and Ross sectional curves. Turnouts are Curtis Hi-Rail and Ross Custom Switches. Mainline curves are O72. Roadbed will be cork instead of Vinylbed.
- Yards: Weirton Junction, Weirton Steel, Coal Mine Spur, Staging
- Command System: Layout will be completely TMCC with the exception of the River Route, which will use a Track Power Controller (TPC-400) to permit both Command and Conventional operation. Turnouts have Z-Stuff DZ-2500A & C switch machines and are both TMCC and pushbutton controlled. Initially, we anticipate 2 DZ2001 switch buses on either side of the bridge.
- Wiring & Power Districts: Wiring will be home-run from terminal blocks located within each district. Track bus wires will be 14 gauge 2-conductor ribbon wire aka zipcord (black / red). Track feeders will be GarGraves connector pins with pig-tails. The layout is divided into 8 power districts (blocks):
- Steubenville (Main Line)
- PRR Bridge (Main Line)
- Weirton (Main Line)
- River Route (separate loop; TPC goes here for running conventionally or command)
- Coal Mine Spur (yard)
- Weirton Junction (yard)
- Weirton Steel (yard)
- Staging (yard)
- Power:
- Eight Lionel 180 watt PowerHouses (8 might be overkill, we'll see) supply all track power to districts 1-8.
- Two (2) K-Line PowerChief 120F transformers supply power to switch machines, signals, and some AC accessories.
- All DC accessories, building lights, traffic signals and street lights get their power from respective 3VDC, 5VDC, and 12VDC power supplies.
- Power Distribution: A transformer cart will be on the floor centrally to the right of the bridge. A distribution panel will be located on the room wall low and near the cart. Features are:
- Panel will be large enough to permit all transformer connections to go to individual terminal blocks for distributing power to the eastern and western sides of the layout. Panel will have spare room for expansion and ease of access.
- Each power district will have an indicator light for its bus. (No, they are not magic light bulbs. )
- All TMCC components will be mounted on the panel.
- All 8 Lionel 180 watt PowerHouses will be mounted on the cart.
- Both K-Line PowerChief 120 transformers for the switch machines and AC accessories will be mounted on the cart.
- All DC power sources for accessories and lights will be mounted on the cart.
- Layout reference and operating manual will go on the cart (I need to simplify my manual).
- Spare fuses, lubricating oil, and smoke fluid will reside on the cart.
- One power strip will control all components, i.e. one On/Off switch.
- Signals: Z-Stuff DZ-1060 PRR position signals (4) & MTH PRR signal bridges (2). The layout is only signaled for travel in the counter-clockwise direction. The reason for that is in the yard discussion that follows.
Yards:
Besides the obvious change in size and car capacity, I believe the yards in 2.0 are better placed and designed.
- Coal Mine Spur:
- This is a trailing-point 2-track yard with a coal tipple. It's on the left (Steubenville) side of the layout.
- The B6sb switcher (shifter) will move empty hoppers in and take full hoppers to the steel mill.
- Weirton Junction / Standard Slag:
- This is a trailing-point 5-track yard located slightly right of the layout's center.
- The top-most spur is Standard Slag. This is a dumping point for slag cars.
- The remaining tracks handle freight cars and empty slag cars waiting to return to Weirton Steel.
- The bottom-most spur (curved) is a caboose track.
- There is an engine pocket on the other side of the mainline, as was in the prototype. A PRR N1s or N2s helper might end up there. Or not. I'm not really sure I want any grades on this layout. They've been nothing but trouble.
- Staging:
- This is a double-ended staging yard that can hold 4 trains. It's located at the extreme right end of the layout. At present I don't anticipate much cutting and assembling trains here.
- The design is still somewhat fluid. I may play with it to try an add 1-2 more storage tracks.
- I added an engine pocket for a switcher (shifter) or storage of the odd road locomotive.
- Weirton Steel Yard:
- This is the only facing-point yard on the layout. That's because it lends itself well to all the push / pull intra-mill operations. A single switch engine (Alco S-2) can move small cuts of cars among all 4 mills with this set-up.
- For slag trains and all freight trains leaving with steel products or empties:
- The switcher will grab a cabin car and tack it onto a cut of cars.
- It will then pull the cars out on the mainline and then push them onto the siding (labeled "R"). This has been made longer to accommodate this run-around move.
- For slag trains, the switcher will then decouple, back onto the main, run forward, and then back onto the siding and couple to the cars. It will then reverse up the main to Standard Slag, dump the cars, pick up empties, and return to Weirton Steel, reversing the steps described in the first 3 bullets.
- For all road freight trains, the switcher will get out of the way. The road engine, either waiting at Weirton Junction or in the Staging Yard, will run up the mainline, back into the siding, couple up, and depart.
- I believe this design eliminates the need for a double cross-over. Ironically, I do have space for one now.
I see the layout allowing at least 2 people to run mainline trains and 3-4 people to perform switching operations.
Comments, suggestions, questions are encouraged! I want to hear your thoughts, now, while it's still a concept.
Thanks!
