Diesel Locomotive Pocket Guide 3/1978

Posted below are Diagrams from the Frisco Diesel Locomotives Vest Pocket Diagrams Rev Y Date 3-78 from the Office of C.M.O.M.P.

 

Sirfold ..... Like most all railroads, the Frisco did a set of locomotive diagrams, both steam and diesel, to allow the troops around the system to keep track of engine numbers, classes, HP, gear ratios, fluid capacities, brake systems, builder, build date, tractive effort, yada yada yada. These were usually in booklets about four inches tall and eight inches wide. They also did similar diagrams for freight and passenger cars, etc.

In the early 1950's, the SLSF started to issue simplified diesel locomotive diagram booklets for the diesel roster - these being only 2.5 inches tall by 4.5 inches long. They called these "vest pocket" diagram books because of their small size. To my knowledge, they only did this "downsizing" for the diesel fleet. I don't know how many issues they put out - I have eight different issues in my collection - the first in August, 1952. The posting from Kieth shows the Revision Y issue of March, 1978. I only know of one later one - Rev Z of November, 1978, which I have. Who knows - they might have started with Rev A, so there could have been 26 of them! As far as I know, the GP50's never made it into the vest pocket diagram book.

You asked about the E-unit diagrams. Attached FYI is a scan of the three SLSF E-unit sheets. These sheets are from a diagram book issued before the vest pocket diagram booklets came into being. They show a bit more information. I've included the diagram for the original E7's, the later diagram for the rebuilt E7's, and the diagram for the new E8's. Note the last two sheets also list all the "Racehorse" names (even though they all were not race horses!).

Notice also that the E7 rebuilds included a regearing, from 55:22 to 57:20 to slow them down to better mate with the new E8's, and to give the E7's a bit more TE.

I picked up the posted Vest Pocket Guide from ebay for $2.99 - just 'cause (Frisco stuff!).

The E and F units were not listed because they were long gone by 3/1978.

The main reason I share everything I can on this site is so it will be archived electronically.

 

Sherrel - As a very frequent "seat warmer" on TWA during the 1980's and 1990's while I was with Monsanto, I tried to get a copy of the TWA "fleet diagrams", or at least a roster listing each aircraft and model number. I had a couple of guys promise to send me one, but it never came.

Must have been against the rules or something! Certainly would be today.

ps - Did you fly in and out of STL much? If you did, chances are I rode behind you a few times! I did STL to Detroit, Salt Lake, Atlanta, Orange Cy, New Orleans, Portland, New York, Miami and Philly a lot.

 

My Frisco E-unit diagrams I posted last night are pretty hard to read clearly. I scanned a xerox copy of all three on one page that I used in some articles I authored a while ago. Sorry about that.

I looked through my "stacks" this morning and found the three source diagrams. A scan of each individual diagram is posted below ..... much easier to read.

Do any of you know any of the details of the MKT E7's for the Texas Special that ran with SLSF 2000 and 2003 on the TS? Does anybody have a diagram of them? I'm interested to see if they were geared 55:22 originally like the SLSF E7's were, and if the MKT then regeared them down to 57:20 when the Frisco regeared 2000-2005?

I think I'll pose that question to the Katy H&TS today.
