    Why are SLSF 2000-2005 often referred to as "EA7" and not E7A?

    I have not seen this designation anywhere except at frisco.org

    What are the retirement dates for SLSF 2000 thru 2005?

    I know SLSF 2000 and SLSF 2002 went to L&N but not when.

    As to your first question, the Frisco locomotive diagram for those units showed those units as EA7 and not E7A.

    Why? Cannot really say. Must have been a Frisco thing.

    Interestingly enough, the E8As were listed as E8's and not EA8's

    Dates Locomotives Retired:

    E7A (EA7) SLSF 2000 - Fair Play - October 1965 - Sold to Louisville and Nashville, L&N 782
    E7A (EA7) SLSF 2001 - Ranger - January 1966 - Traded into EMD
    E7A (EA7) SLSF 2002 - Comanche - October 1965 - Sold to Louisville and Nashville, L&N 783
    E7A (EA7) SLSF 2003 - Steel Dust - January 1966 - Traded into EMD
    E7A (EA7) SLSF 2004 - Dan Patch - October 1965 - Sold to Louisville and Nashville, L&N 784
    E7A (EA7) SLSF 2005 - Winchester - January 1966 - Traded into EMD

    Many thanks.

    Do you also have the retirement dates for the E8As?

    According to EMD documentation, the original designation given the E series passenger A units up through the EA7s by EMC was EAx where x was the series number.

    Beginning with the 8 series, EMD changed the designation to E8A for A units and E8B for B units.

    I refer you to Ken Wulfert's (meteor910) post in this thread:

    http://www.frisco.org/shipit/index.php?threads/whats-the-difference-between-the-e-a-7-and-e7.3849/

    I think that most of the rest of people want a nice continuity in designations and since everything from E8s, to E9s and F units follow the Alpha, Numeric, Alpha format, they refer to the predecessors likewise, despite EMD documentation to the contrary.

    No less a diesel expert than Louis Marre referred to them as EA's in his Frisco Diesel Power book.

    What is really confounding is that Louis Marre, in his 2012 book The Diesel's First 50 Years published by Stephen Priest's Paired Rail Railroad Publications, refers to these EMC E units as E7As.

    I was just looking at my copy of Frisco Diesel Power and Marre uses BOTH designations, EA7 and E7A!?

    The above information came from a spreadsheet posted on this site, but darn if I can find it now. I wanted to credit whomever posted it and where it is located.

    I also updated my original response as to what L&N numbers they became.

    Shows how observant I am. I had never noticed the EA7 orientation.

    I think I had just assumed that they, too, were E7A. To my eyes and brain, EA7 probably looked too akin to FA-1.

    I do not know much about when Alco rolled out their FA-1s and FB-1s, but would that have potentially been a mitigating factor in EMD's decision to reorder their designations?

    Something new for me to learn every day around here.

    I have learned that I cannot completely eliminate my ignorance, but only strive to reduce it. :)

    Best Regards,

    The MKT used the EMD classification, EA-7, in its diagrams as well.

    Ah, Chris, how nice it would be if we all strived to reduce our ignorance instead of being satisfied with it.

    There is nothing wrong with ignorance, simply a lack of knowledge of a subject, but staying in it is inexcusable.

    I believe EMC also wanted some common terminology for their new models.

    As the FT, F2, F3, F5 (unofficial), F7 series came along with their immense popularity, to be followed by F9s, FP7s and FP9s

    EMD lost their affinity for the term "EA-whatever" for their popular E-units, so the E8 and E9 terminology was adopted.

    Do any of you have a decent picture of E7A (EA7), take your pick, SLSF 2002 in its original Meteor paint scheme or livery?

    This would be the original E7A (EA7), not the later modification to a "Racehorse" to match the E8As.

    Thanks.

    Ken,

    I believe this is the best we can do.

    Two Mike Condren photographs in black & white, SLSF 2002 and SLSF 2005.

    One of SLSF 2002 from the Stuart Kurth collection

    A Hallmark E7A (EA7) decorated as SLSF 2002.

    Thanks Keith!

    The first one of 2002 is just what I needed.

    Terrific.

    OK, I need to come back to the well for another picture of SLSF 2004.

    I am trying to prove a point, so I want a picture of all six E7As (EA7') in their original colors, two for the Texas Special and four for The Meteor.

    So     I need a nice legible picture of SLSF 2004 in its original paint scheme to add to the other five I have. Black & white is fine.

    This is what you have to do to prove something simple to a northeast railroad fan, although he is a nice guy.

    He knows the MKT also had two units for the Texas Special.

    Thanks in advance if you can help.
