    To All:

    In researching the SW1500 project for Athearn I have found that most of the locos spent their lives looking basically the same. I have found a picture of two of them that had the stock horn moved to the top of the cab roof. Ken Wulfert seems to think that this was done for better grade crossing protection.

    Having said that does anyone remember anything unique about any of these locos. I would be especially interested to know the following:

    (1) Did any of them (specific road #'s) spend most of their career at a specific yard or city.
    (2) Were they all assigned to a specific service point (i.e. Springfield) and lettered so or maybe more than one.
    (3) Anything else about any specific loco or locos anyone can remember.

    Thanks in advance,

    A few of them had that second little multi-bulb "light thingy" mounted on the roof.

    The roof mounted horns were put on some of the SW1500's that did transfer work running out to other rr's, or did switching outside of the yards, as it was a bigger horn and higher mounted - made more noise for the grade crossings.

    As far as I know, roof beacons (I think thats what Ken was trying to say) were a standard on the SW1500's, and all other 2nd gen power for that matter.

    The Frisco's Roof Beacon of choice was the Prime Stratolite. It consisted of four fixed position lamps aimed at 90 degree intervals with a control circuit that turned on one lamp at a time in a stepped, circular pattern, simulating a rotating beacon without the need for revolving parts and electrical connections. All of Soundtraxx's sound and mobile decoders provide the Prime Stratolite as a lighting function option.

    Ethan and All:

    What Ken is referring to is a small appendage on the top at the rear of the cab that looks like a smaller light. By what he says if I understood his post is he may think it is the two light (horizontal) post that some of the extended vision cabooses had. I think it looks different than that, more like a small light of some kind.

    Right - I'm certainly not talking about the large "Stratolight" "rotating" roof-top beacon (Details West RB-106) that all the Frisco SW1500's carried, but instead the smaller, tall light on a thin support stand that is also on the cab roof, centered at the very end of the cab, on many of the SW1500's. It looks like the older style flashing roof beacon that many of the earlier switchers carried. I had always thought the rotataing beacon was on the SW1500 as delivered from EMD. But, maybe not - perhaps they put the older style on some after delivery, then they liked the rotating one better, but left the older one up there on some units.

    Who knows? More Frisco mystery!

    Ken

    ps - I just quickly ran through my SW1500 pics again. It also looks like there was not a standard modification plan to the horns - some went up on the roof, and some got replaced on the cab front but with a bigger, or multi-chime, horn. Perhaps each shop put on whatever they had if they decided to improve the horn sound.

    More .....

    Notice the Frisco SW1500 pictures on pages 35 and 36 of Marre/Sommers' "Frisco In Color", vol 1. The SW1500's obviously did not all come with the rotary roof beacon already installed - it must have been a Frisco applied item. Note the smaller flasher beacons located at the back edge of the roof on some of the SW1500's on these pages. For some reason they left these on when the bigger rotating beacons went up there.

    I love this railroad ..... I learn something new each day via frisco.org!

    And more .....

    Attached is a pic of brand new SLSF 315, the class SW1500, at Lindenwood (I think). This is from the 1968 Frisco Annual Report.

    This does not answer the question as to were the beacons EMD applied or Frisco applied. But, when brand new, SLSF 315 had both beacons up on the cab roof. Note for the pic, the headlights and the small beacon were turned on, but not the rotating one.

    I consulted my books (frisco in color - Marre and Sommers. And frisco diesel power - Marre and Harper) and see what ken was referring to now. I have never noticed these before.

    Here's what I gathered: the earlier units had the small strobe, while the later ones didn't. In frisco diesel power page 114 there's a picture of 345 parred with 565 on oct 13 1979 and 345 is sporting a small beacon but not a large one. Same book page 112 348 & 349 are parred together on April 30, 1980. Both have the big beacon, but not the small. Page 113 has 329 on may 28 1972 with both large and small. Page 105 shows 360 And 355 in August of 75. Both hav a large beacon but not a small.

    So from what I can conclude, some were between 345 and 348 they stopped adding the small beacon. And it was not removed towards the end of their lives.
    Any one have a list of the batches the sw1500s were ordered in to show were the split is?

    Ken and All:

    Maybe this will solve the mystery on at least some of the units, and then again maybe it won't! There is a beautiful picture on the bottom of page 94 of Greg Stout's new book Frisco in Color, Volume 2 showing brand-spanking new SW1500's #336 and #333 at Chicago waiting for delivery to the Frisco. They clearly show the large rotating beacon already installed.

    As far as the small light or beacon, I encourage those of you that have this book to browse through it and you will notice that numerous other switchers clearly have the small light mounted on the top including FM units at Tulsa. Maybe Terry J. (tmfrisco) can weigh in here as he operated them in Cherokee Yard but I am beginning to believe that they may have been installed higher to facilitate visibility in yards.

    Having said that, I can't think of a manufacturer that produces this smaller light. If anyone else can, please post.

    So it would be safe to assume that 347 on up did not have the small light. And what about 343-346?

    I'll do some digging around on the internet and see what else I can find.

    Oops! My Bad!

    343-346 Jan. 1970

    This comes from the book Frisco Diesel Power which I believe you said you own.

    One thing you can do, which I have done on my FM H10-44's, EMD NW2's and EMD SW7's, is to use the Details West RB-126 Western-Cullen Rotary Beacon part. The vertical support shaft is too thick, but you can make it tall enough to simulate the small flashing beacon. I guess you could cut off the too-thick shaft, and put a thinner rod on it to simulate the thinner support shaft, but I have not bothered to do that.

    The SW1500's may have been fairly uniform right after delivery, some with two beacons, some with only one, but once they started messing around with the horns, there were a lot of different small details. Bob and I are awaiting more SW1500 pics to evaluate. Our objective is to pick three representative Frisco SW1500's, each with a few different details, supported by pictures of the specific units, to support Athearn's proposed new Frisco models.

    After doing more looking here are some more of my thoughts:

    As railroads looked to cheapen operating costs, they started taking off the extra lights (Like BN did.) And I've noticed that the beacons started disappearing in the late 70's. From what I've seen most of the time if the switcher has one or both removed, its paired with another that has at least the big beacon. Some times only the big beacon was taken off, some times both. Look at Frisco In Color on page 36, 329 is paired with 362. 329 does not have a big beacon, but still has the small one and 362 has a large beacon. Then look at this photo: http://rrpicturearchives.net/locoPicture.aspx?id=130523 346 still has both, while on 322 both have been removed (I had to zoom in quite a bit to see it). Why they chose to remove it on this one, and not the others, we may never know. But it's safe to assume they wanted at least 1 big beacon in the consist, and so if that's true then it would be safe to assume that those units with out beacons were stuck with which ever unit they were paired with.

    Any one else have thoughts on this?

    How would we go about having athearn work with mixing and matching?

    I think the modeler should study photos and add or subtract beacons according to the engine being modeled. I don't model that era, but if I did I think I'd add a beacon to my engines. There sort of neat kind of like Mars Lights of the first generation diesel era.

    Tom is exactly right. What Bob and I propose to do for Athearn Genesis is to select three SLSF SW1500's, each with a different specific combination of "accessories", well documented by photos of at least both sides with end views. The combination of accessories would involve the two different roof beacons, the wide variety of horn types and horn locations, and whatever else we can find. There may well be some alternate window modifications, and a shop-added vent or two we can consider. We also will try to spread out the date of the unit a bit, so they are all not from the same time.

    I believe I read some where that the smaller strobes were there so the unit could be seen more clearly from yard towers while sorting cars. Larry F.

    To All:

    I must admit that I feel that I spurred an active discussion about the SW1500 and hope we all learned something we didn't already know or
    realize which admittedly is a always a good thing. Having said that look back at my original post above and note that I asked 3 questions and that even through we have had a lively discussion thus far, I feel that only one (#3) has had any discussion or been answered.
    The reason for my original query is in suggesting road #'s to Athearn I had hoped to pick ones assigned to different specific points on the system if that was indeed the case. As an example, NW2 #261 spent a great part of it's life assigned to Wichita as the yard switcher. It was then replaced by GP15-1 #102 which did the same. Hopefully we can assume that the SW1500's did not regularly see duty in the Tulsa and surrounding are as that was FM country. Also, there may have been some in Birmingham, but the MP15's were assigned there. So two questions remain:

    (1) Does anyone remember seeing a specific unit or units spending significant time in a specific location? When I lived in KC for a year in the late '70's I remember seeing a unit always spotting at Olathe for instance.
    (2) Were these locos assigned to different service points around the system or always returned to Springfield for maintenance. If the latter is the case then they indeed may have been rotated around the system.
    (3) Was the service point stenciled on the front edge of the frame. Look closely at the Athearn picture I referenced and one can easily see the word "Springfield" behind the customary "F". By looking at the pictures in the books there is something there but to me it looks like some sort of owners plate as it is shiny.

    Thanks again everyone!

    Keith -
    I really appreciated this description. As a kid, the Prime Stratolite was typically always running on the units that would sit near the Chaffee depot in the late 1970s, and certainly on the lead unit of trains that would stop for a crew change.

    I'd never realized that there was no rotary mechanism until pre-merger BN power began appearing in Chaffee. Their orange beacon most definitely rotated, and was a not-at-all enjoyable contrast to the SL-SF units.

    For what it's worth, my little Blue Box SW1500 has a Details West beacon mounted topside. I have an old effects kit (I forget the manufacturer) that I hope to rig up and have the beacon look "close enough."

    Best Regards,
