Purpose for the Railroad
-----------------------------
The Pennsylvania & Western is a fictional subdivision of the PRR. It is envisioned as an alternate east-west route between Altoona and Pittsburgh (much like the line through Hollidaysburg and around Muleshoe Curve), with a connection to the B&O and Western Maryland railroads in Cumberland, MD. The principal yard is located in Annville, PA. Annville is not a major division point, but many trains stop there and there are minor locomotive service facilities as well. This and the other towns on the layout are fictional and not meant to prototypically represent any particular Pennsylvania location. For example, there is a real Annville, PA but it was never served by PRR. Lebanon on the PRR was an interchange point with the Reading RR, and it is also on the P&W. In reality, however, Lebanon, PA is quite a bit east of P&W country.
The time period is 1951 to 1954. Some of the locomotives on the railroad were retired by PRR in 1951, and some of the cars have the "shadow keystone" theme introduced in 1954. Typically for PRR in this period, there is quite a variety of steam motive power. Pennsy's early diesel experimentation is evidenced by the variety of diesel power from Alco, Baldwin, EMD, Fairbanks-Morse and Lima-Hamilton. Steam locomotives are nearly all brass imports from Weaver, Williams and 3rd Rail with new diecast switchers from Weaver and K-Line. Diesels are plastic from Weaver, Williams, K-Line and MTH.
Harrisburg, Enola Yard and the Petersburg branch are located to the east of the modeled portion of the railroad, with Pittsburgh, Conway Yard and Shire Oaks Yard (coal marshaling) to the west. Cumberland, MD and the B&O and Western Maryland interchanges are to the south of the modeled portion of the railroad. These off-layout locations are represented by staging yards. There are 6 main staging tracks in Harrisburg and Pittsburgh, along with 2-3 shorter ones in each location. Cumberland, MD is a staging yard with 3 tracks and is located underneath Horseshoe Curve and Lebanon. The mainline is 550 feet long, which is 5 miles in O-scale. There are six main towns along the line and a couple of minor ones. There are about 40 destinations for local freight switching activity.
The layout was designed with operation in mind. That is, the purpose of the trains is to move freight and passengers in a prototypical manner. The movement of cars is determined using a commercial car-forwarding program (RailOp) that runs on my home computer. The software determines car routings, assigns cars to the trains and prints switchlists for the train crews to use. There was a lot of setup work to do prior to using the program, but it seems to have been worth it.
Train Speed Issues
----------------------
I designed the Pennsylvania & Western to include several speed-limiting elements, with the primary goal to make the mainline run seem longer. A helper grade, speed restrictions within yard limits, within tunnels, and while crossing curved trestles, stops at the top of a downgrade to set brakes and at the bottom to cool brakes, etc. were all included. Locomotives in my chosen era are primarily steam rather than modern high-horsepower Diesel power. Steam moved slow in the mountains. Freight trains are restricted to a maximum speed of 40 scale mph and passenger trains to a maximum of 50 scale mph. All trains are restricted to a maximum of 30 scale mph when crossing all trestles.
Motive Power and Cabin Cars
----------------------------------
The P&W motive power roster is a mix of steam and diesel. You might see L1s, I1s or J1a freight power and K4s on the passenger runs. The P&W shop foreman is a fan of streamlining, and he has re-applied the skirting to some of the K4s. Other classes of Pennsy steam power such as B6sb, C1, H10s and T1 can be spotted on the line as well. The diesel fleet contains representation from most of the builders of the period: Alco (FA-2 and RS-3, PRR classes AF15 and AS16, respectively), Baldwin (Centipedes and Sharks, PRR classes BP60 and BF16, respectively), EMD (F-3, E-7 and E-8, PRR classes EF15, EP20 and EP22, respectively), Fairbanks-Morse (H10-44, PRR class FS10) and Lima (2500 hp transfer diesels, PRR class LS25). Not all equipment runs in every session, so you might have to visit repeatedly to see it all! Trainphone antennas are present on some of the locomotives, and eventually will be applied to nearly all of them.
To support prototypical operation, some modifications to P&W motive power have been performed. Most importantly, all locomotives have been converted to TrainMaster Command Control (TMCC) and most have sound. Most of the conversions used Digital Dynamics parts and the others used TrainAmerica Studios components. I highly recommend either supplier. Steam engines have had front couplers added so that double-heading and local switching are possible (pic). The couplers are diecast dummys and are smaller than the typical Lionel knuckle, yet mate with 3-rail couplers perfectly. Since they are smaller, they look better on the locomotive pilots than would the Lionel dummy coupler. The ones I used are sold by Bowser under the Selley product line.
Williams diesels that had high-gloss paint have been sprayed with Testor's Dullcote which greatly improved their appearance. Since Williams diesels typically run very fast, they have also been rewired during the TMCC conversion process so the twin motors are in series rather than in parallel. This GREATLY improved their low speed performance! Original Williams headlight bulbs were also replaced with 16 volt grain-of-wheat bulbs mounted directly into the headlight lenses. This produces a bright headlight without bleeding into the undetailed cab interiors.
Cabin cars (called cabooses on other railroads) on the railroad consist of N5, N5c, N6b and N8 classes. Local freights sometimes are assigned an ND 4-wheel bobber. Most of the cabins have Trainphone antennas installed.
Rolling Stock
---------------------
Most of the freight cars on the layout are Weaver or others of 2-rail heritage. There are a few MTH and K-Line, but I tend to buy most of my rolling stock at 2-rail train shows. You can find nice cars, sometimes weathered, for $20 or less at the scale shows. Weaver diecast trucks and couplers work well to convert the 2-rail cars to 3-rail. I have added weight to all cars, so they now meet the NMRA standard of 5 ounces plus 1 ounce per inch of car length. Some cars are slightly heavier than this. The method I use is to add lead shotgun shot (size #7.5), glued into laboratory weighing boats that are in turn glued to the car floors above the trucks (pic). I use rubber cement to hold the weights, so they are removable if the need arises.
Some of the 2-rail cars that I've converted to 3-rail are from Pola (pic), Crown with weathering (pic), Atlas from the 1970's and custom repainted and relettered by a 2-railer (pic1), (pic2), Intermountain (pic) and custom-built from a wood kit (pic). These cars are different from those found on most 3-rail layouts and I didn't pay over $20 for any of them!
Operating Positions
-----------------------
The layout is designed to support 6-10 operating positions for a "full-fledged" operating session. The positions are as follows:
Dispatcher - Responsible for the flow of traffic on the railroad by coordinating the running of passenger, through and local freight trains according to the sequence or schedule.
Annville Yard Master - Responsible for ensuring a smooth flow of traffic into and out of the freight and passenger yards at Annville. Access to the yard is under the Yard Master's authority, as are all movements within the yard limits.
Annville Shifter - Responsible for sorting Annville yard tracks, making up and breaking down of local freights, switching the ice tracks, Railway Express, Annville power plant, and engine service tracks (sand, coal, ash).
Through Engineers (1-2) - Responsible for running through passenger and freight trains. May do a limited amount of local work / station stops during the run.
Snapper (Helper) Engineer - Responsible for adding the snapper locomotive to westbound trains at East Valley, following train to Annville, detaching snapper, and running locomotive light back to East Valley.
Local Freight Engineers (2-3) - Responsible for operating local freights that originate and/or terminate in Annville.
By eliminating some trains (running a "Sunday schedule") we will be able to eliminate some of the local freight and through freight jobs, the snapper engineer, and the dispatcher can be combined with the Annville Yard Master. We should be able to get by with as few as 4-5 operators. The local freights could easily be 2-person crews, so up to a maximum of 10-12 operators can be accomodated.
Communication and Signals
----------------------------------
We use Maxon or Radio-Shack 2-way radios with headsets to communicate among the operator positions. This simulates the PRR Trainphone system that was in use during 1951-54. The use of radios greatly enhances the illusion that operators are isolated from each other. Block occupancy signals on the layout use PRR position light signals. Most signals operate automatically using relays for occupancy circuits. The approach signals to Annville will be controlled by the Annville Yard Master, and approach signals to Lebanon, Summit and East/West Valley can be controlled by Local Freight jobs that are operating there. Local freight crews act as the town Tower Operator and set the approach signals at the direction of the Dispatcher.
Car Forwarding
-------------------
Initially, the layout will be operated using computer-generated switch lists and a sequential schedule for trains. Sequential scheduling will put less pressure on our crews than would a fast clock schedule, and the dispatcher can adjust the number of trains on the railroad to match the skills and experience of the operators. I've operated using car cards/waybills and using switch lists, and each method has its strengths. Car cards/waybills are more flexible and "forgiving" in the event of errors in car routing, but switch lists seem easier for new operators to use.
I am starting out with a computer program called RailOp that generates train makeups and switch lists. There is a lot of data input to get the program running, but it seems like it will realistically route cars, handle loads and empties, etc. like I want it to.
The Trains
---------------
The initial operating sessions will consist of 17 trains. General through freight, coal drags, local freight and through and local passenger trains will be run. The train list is shown below. Following PRR practice, passenger trains are designated by number only while freight trains have a letter code describing the origin and destination, followed by a number. Even-numbered trains run westbound and odd-numbered trains run eastbound.
