The Pennsy Modeler

In order to portray Pennsylvania Railroad and interchange partners as accurately as possible, this blog contains articles which are essentially notes to myself, but are shared should the community desire the same information.

Articles are sorted by modification date, so if an existing article receives an update it will be presented at the top of the list again.

MANUAL BLOCK SIGNAL TERRITORY

A Manual Block Signal system, the earliest form of block signaling, is nothing more than a series of sections of track, typically between stations (known as blocks) governed by fixed signals located at the entrance to the block (known as block signals), operated manually by the block operator, based on information received from the dispatcher by telegraph, telephone or radio.

As of 1923 (interpreted from Form CT1000), the Pennsylvania Railroad was organized into Regions, Divisions, and Railroads. Railroads represented in bold are included in the listings but are believed to be independent railroads (many are confirmed so).

The F30 were 50' flat cars and the predominant flat car class on the Pennsy roster during the 1950s.

As of 1884 (interpreted from Form 76), the Pennsylvania Railroad -- which did not include "Lines West of Pittsburgh" -- was organized into Grand Divisions, Divisions, and Railroads. Railroads represented in bold are included in the listings but are believed to be independent railroads (many are confirmed so).

When is an EMD "F7A" an "EF15a"? When it's owned by the Pennsylvania Rail Road!

The Pennsy - The Standard Railroad Of The World - had its own system of classifying diesel locomotives, rather than relying on the designations appointed by the builders of the units.

With very few exceptions, the Pennsy's diesels were classed using the following multiple character formula:

Andy Miller (PRR_Talk list) shares his thoughts on the HO scale Pullman Sleeper offered by Bachmann Spectrum:


I finally got a Bachmann Pullman today. Why does B do these things?? Its terribly frustrating to see them do such a fine job of mold making, include interiors, metal truck, lights, Kadee-compatible couplers; and then just ignore the prototype!

I did some research. This very rare car did exist. For those interested here's what I dug up in the Wayner reprint of the Pullman Co's 1950 list of cars:

1956

The economic success of the railroads depended on freight shipped in full cars. The idea of putting truck trailers on flatcars was a method of moving less-than-carload shipments economically. This "intermodal" concept held the hope of competing with trucks which were taking more and more of this business from the railroads.

In the mid-thirties, the Chicago, the Great Western and then the New Haven railroads began piggy back service limited to their own railroad. By 1953, the CB&Q, the Eastern Illinois and the Southern Pacific railroads had joined the innovation. Most cars were surplus 50's flatcars equipped with new decks by the railroads. By 1955, an additional 25 railroads had begun some form of piggy back service. A significant legal battle between the truckers and the railroads resulted in a ruling permitting interstate piggy back service using either railroad or privately owned trailers. The stage was set for rapid expansion of intermodal services.

Bob Johnson's comments, as coordinator of the archives of the PRRT&HS:

1 - As built in 1-1929 to 4-1929 the cars had no side ladders and had the end ladders on the right side of the ends as you stand facing the end of the car. The side sill steps at the ends were a two-step style.

2 - About 1932 some, but not all, R50B cars began to receive freight car safety appliances. This added side ladders, changed the side sill steps to a single-step type, moved the end ladders to the left side, moved the brake wheel, added a brake platform, added a platform above the end ladders, and modified many handholds.

3 - On 4-3-1940 a second handhold was added on the left end of the sides of R50B cars with freight car safety appliances, but not to cars that kept the original configuration.

4 - On 12-18-1942 the end details described in #2 above were made standard for all R50B cars. This made a new variation with full freight car safety appliances on the ends, but no side ladders. I haven't seen any photos of this variation.

5 - Beginning in 1952 the running boards and side ladders were removed.
