Santa Fe 185L

Post by SSW9389 » Mon Aug 28, 2017 10:36 am

This March I picked up a copy of Iron Horses of the Santa Fe Trail. There's a photo of a very interesting FT A unit on page 450. I've stated that it's really an F7Am, and don't you know that started several brouhahas with Santa Fe experts. It appears to have been rebuilt at Cleburne in late 1951 or early 1952. I'm searching for wreck photos and details. Several photos of the wrecked 185L have been posted to Trainorders, but not the profile view necessary to determine frame damage.

If you find photos of this interesting unit look at the position of the trucks. Both appear to be forward of their normal position on an FT A unit. And note the amount of frame overhang at the back of the unit.

Does anyone have the as-built plans for EMD order E709, that's the order that the 185L, ex 179C was built on in August 1945.

Thanks for any reply,

The FT internal layout is completely different. The FT would have been completely gutted and start from scratch to have anything similar to a F3 or F7. ATSF had the square dynamic brake box on the roof of the FT The D4 generator would not accept a higher rating so that will mean a new D12 generator or the HP stays at 1350HP as in the GP7m built from a wrecked trade in FT.

My point about the rebuilding of the 185L is that it was rebuilt on a new F7 underframe. The F7 was over two feet longer than an FT and had a longer wheelbase. And that's why a decent profile photo is needed to identify where the trucks are in relation to the carbody.

FT units used the D8 generator, not the D4.

The D4 main generator was used in all FT,F2.E3 thru 7 unless a trade in locomotive was used. as in ATSF E8 that used the GE 5GT544 main generator from trade in locomotives.The E8 thru 9 used the D12 main generator. F3 thru F7 GP7 used the D12, F9, GP9 and E9 used the D14 main generator and again unless other generators used from trade in locomotives.

It was the D8 generator that was used on all FTs and F2s. The D4 was used with the 1000 horsepower 567 and 567A engines. See "All About F's" by Don Dover in the January 1970 issue of Extra 2200 South. I have Folio sheets from two railroads showing D8 generators in FTs, there are likely more Folio sheets online which will show that same fact.

The D12 was a main generator, the D14 was a companion alternator for accessories.

There's a .pdf file on the Northern Pacific Railroad Historical Association site that has the FT folio sheet showing the D8 generator. It's on page 2 of the Folio diagrams: http://www.nprha.org/Pages/Equipment.as ... ocomotives

Just found a third EMD document that was sent to me by Preston Cook years ago. The EMD plate drawing 2888 is for Santa Fe FTs delivered in February 1942. The generator shown on the EMD document is the D8.

The generator used on the E8 was the D15A with companion D16 alternator for accessories. The generator used on the E9 was the D15B also with the D16 companion alternator. Source Extra 2200 South Issue #43 p.19 Spec-Profile. The F9 and GP9 used the D12 generator with the D14 companion alternator.
