Norm The Keil Line part is #4855 – EMD Car body Lifting Lug set (both ends). Scale City Designs bought Keil Line and is reissuing many of the sets under their brand. When I checked their on- line catalog for a different part it wasn’t listed – but had it in stock. Scale City Designs is an OGR Forum sponsor and has been responsive to my queries – worth an email or phone call .
I just got back from vacation and had the opportunity refresh my knowledge of PRR F unit details and lettering. We are fortunate to have two very well researched pubs to guide PRR F unit modeling. The most in-depth document is a two volume 137 page study by Jack Consoli entitled “The PRR F-Units” published in the PRRT&HS’s The Keystone Vol. 37, No. 3, (Autumn 2004), and Vol. 38 No. 1 (Spring 2005). Complimenting The Keystone articles is Paul Wither’s Pennsylvania Railroad Diesel Locomotive Pictorial Volume 6 – EMD and ALco Freight Cab Units. Below is a general outline of changes made to notable appearance elements of PRR F units extracted from the above sources. For far more detailed info about these and other changes made to PRR F’s read The Keystone articles. Note - post delivery modifications, often recorded as “Betterments” for tax purposes, were phased in as units were shopped. Therefore the dates below are offered as a general guide - not an absolute rule.
As delivered 1950-52
- Lifting lugs on nose and B end of car body
- Coupler covers (several styles)
- Diaphragms on B ends
- Single or triple forward facing horn on engineer side (No rear facing horn on fireman side as on AtlasO F7)
- No grab irons over front windows (except last 8 F7 units which had distinctive Far-Air grills)
- No ladder rest irons on nose
- 2” single stripe (larger radius nose curve than on AtlasO F7 - IMO it's most noticeable flaw)
- Number in nose keystone
Circa 1953-54
- Grabs added over the front windows
- PRR monogram keystone replaces number keystone on nose
- Ladder rest iron applied on each side of nose (AtlasO F7 has an incorrect grab below the ladder rest)
- Diaphragms removed
Circa 55-58
Circa 1959- many changes
- Five grabs and a step added on engineer side of nose
- Pilot MU hoses added
- Fuel tank skirts removed
- Spark arrestors on some units
- PENNSYLVANIA lettering removed from sides of some units
Having consulted on several O scale PRR locomotive projects I understand how easy it is for tooling designers to make mistakes when harmonizing era and railroad specific details. To minimize confusion, my general recommendation to importers is to produce diesels with as delivered details for a specific order lot/phase as there generally are good photos available to guide the effort. If they are going to offer locomotives in a post production configuration, they should provide the designer a set of well annotated photos (taken in the same time frame) to detail how the unit differs from the as-delivered configuration.
For those that don’t want to sweat the details – enjoy the MTH, Sunset 3rd Rail, and AtlasO PRR F’s as they are.
