BN 2550-2566 series of ex-Frisco's 'Torpedo Tube' GP35's... does anyone have any overhead rear shots or diagrams that show the routing of the airlines? There is a couple of images taken from ground level that show the airline disappearing into the rear right end just above the numberboards but none higher up showing the left side. Also, the positioning of the air tanks themselves either side of the dynamic brake fan. The fore/aft positioning is reasonably well documented with images, and the drawings on Michael Eby's site, but the side-to-side spacing isn't. Thanks in advance for any information.
UNless you can find a pic from George Elwood's Fallen Flags site, I'm not sure how the air lines ran. And my copy of Frisco In Color is about 762 miles away from me.
Only two roads had them, SLSF 700-716 and C&NW 844-863... C&NWs lacked dynamic brakes. Enabled the use of a larger fuel tank. Gats, I think I have drawings somewhere of the C&NW version... Both photos courtesy Fallen Flags... please donate to them.
Thanks Robbman! I was unaware of the C&NW version. There were drawings in the Jul/Aug (?) Model Railroading of the SLSF version according to the MR mag index site. I think I have the front airlines nailed but the back I'm not so sure of. The do appear to run straight from the tank to the downturn on the right rear but the left side I'm not sure of. Any help greatly appreciated.
Wow. When I was in HO I was working on a TT GP-40 cause I liked the look for my Pacific & Eastern. Never knew there was almost a prototype. That Frisco scheme is another one that I had not seen before.
When Frisco first took delivery of their torpedo-boat GP35s, they were in black with yellow striping. After the O/W scheme was introduced in 1965, they ere eventually painted in that scheme. IIRC, the extra fuel capacity was so that the GP35s could be used in Santa Fe pool trains, such as the QLA, QSF and CTB.
Kurt, that would be those in the third order, SLSF 725-731 with trucks from retired FA/B-1's. They became BN 2575-2581. Appears SLSF 732/BN 2582 (the last '35 in the third order) had Blomberg B trucks.
That's right Gary- it did come with Blombergs. Not sure why, unless they didn't have any Alco trucks left to use.
There would have imagined there should have been plenty. There were 32 A-units and 16 B-units. Maybe they had left the property, or ear-marked to leave elsewhere, prior to the third order? Hmmm... this is turning into a Frisco thread in the BN forum. Can't have that now!
Would be interested if you find an answer on these - a CNW torpedo tube GP35 is on my 'one day' list, I think I have most of the parts (including an undec non-db GP35!) but there's not many online pics of these about.
Martyn, there have been articles on both units. If between us all we can gather the diagrams/drawings that have been published then we should be set for either unit. AFAIK both were EMD supplied so there shouldn't be too much difference between the airline routing. Famous last words? If it wasn't for the half bottle of Penfolds Bin 389 (available in the UK from Oddbins, BTW) on board I'd get into the boxes of mags and find those c.2000 Diesel Era and ModelRailroading mags....:lightbulb:
Oh, I don't know........seems that the BN forum could use a shot of class now & then (ducks to avoid incoming fire)
Sounds like a plan! Let me know if there's articles you haven't got and i'll see what I can dig up... Maybe! "Things that you would think were simple" might be a good title for a new thread somewhere!
Hmmm... this may qualify for Stupid Mistake 62 - thinking it would be simple. Got the Diesel Era issue with BN's ex-Frisco GP35 TT's and the drawing is in there. Looks a little different to that posted by Mike (SLSF Nut) in the Frisco FF forum and a lot different to what I thought it was! I'll get a scan of it done once I have the PC back on it's feet.
Juggling a couple of the disposition tables in Marre and Harper's Frisco Diesel Power... Most of the Frisco FAs and FBs were traded in to GE in the mid to late 1960s for U25B and/or U30Bs. EMD recieved a total of 13. The disposition table states that 7 were sent in 1-1966, and the rest in 2-1967. All of the units traded in to EMD appear to have been repowered with EMD engines. Since SLSF725-732 were delivered 12-29-1965, and this is the group where 7 of the 8 had alco trucks, I can only speculate that the FAs and FBs were not officially removed from the roster until after delivery of the replacement units. The grup of Alco units traded in to EMD in 1966 included 4 FAs and 3 FBs. The remaining FAs and FBs that EMD recieved were apparently traded in on the first order of SD45s (SLSF 900-911). This second group consisted of FAs only. Here's some other important information for BN modelers of the late 1970s, Starting in February 1979, some of the Frisco actually leased some of it's GP35s to BN. 9 went in February, and 16 additiona units went later in the year. Apparently, none of the Alco truck units were involved in the lease, but the Torpedo Tube units were. (this little tidbit comes from some of the Captions in the previously mentioned Diesel Era[ article). Paul
IN the book Diesels of the Western Pacific (not sure of the title), there is a pic of a BN freight with the usual BN power, but also a Frisco GP35 "torpedo boat" and WP U-boat. The caption mentioned that the Frisco '35 was on lease to BN.
If you want info on Frisco Torpedo Boat GP35s, check out www.frisco.org for a modeling thread including rooftop piping drawing: http://www.frisco.org/vb/showthread.php?6451-GP-35-(Torpedo-Boat)-Modification and for a rooftop picture: http://www.frisco.org/vb/attachment.php?attachmentid=20655&d=1349114103
FYI, you posted to a thread that has been inactive since June 2006. Also, a few post up you'll see GATS found in the diesel era magazine the proper routing.
