    John, cheers, I didn't know 3rd rail did early SP Mallets, especially the AM 2, I'll have to keep an eye out for one of those when I get my Xmas bonus :thumbs:

    The Vandy I'll try and track down tonight as there's several versions. You don't often see photos of tenders back in the day, especially nice well lit views like this.

    Photographers tended to use film on more important subject's like engines, so I expect this is an official photo. I just wish it had been a whaleback, still I grabbed it anyway.

    As far as I know these are the only copies of these images, they didn't come from one of these copy houses you see on EBay but from an estate. I suspect there are copies and the original negatives will probably be in a state collection or something. I'll scan a few more tonight.

    I don't think I have the time to scratch build a SP engine so may just opt for the best RTR I can find and afford and then detail as best possible. Later AC classes would of mixed with early diesels but possibly in the Black Widow scheme, can't remember exactly when the bloody nose came in. The AC-1 were extant by 1948 which I think was the first year the FT came out, you could probably justify a FT ABBA demo set alongside an AC-1 ;)

    Few more this evening.

    First up a AM-2 Ex MM-2, rebuilt to simples and front truck changed to a bogie after a couple of accidents.

    SP 3902.jpg

    Photo was taken at Eugene OR Dec 7th 1938

    Next up an AC-3, bit of an odd bird this one as it has been retro fitted with a bow fronted cab and low domed roof. I've not read or seen any other images of this modification, either on this engine or any other early AC's

    SP 4037.jpg

    Location is Klamath Falls OR June 9th 1948

    Next up an AC-4, not many in this class, only ten engines formed the AC-4 class but they were the forefathers to all the modern cab forwards and set up the basic format for all to follow, namely 4-8-8-2. Front sheet was square from top to bottom, previously it was tapered below cab floor level and new high domed roofs became standard. Tenders also changed from whalebacks to large Vandys. Note angled flag stick holders on the front face below cab floor level.

    SP 4104.jpg

    No date or location given.

    Finally for this evening one of the ultimate AC-12 cab forwards. Bow ended cab front, domed cab roof, enlarged intercooler grills, low level hooter, boxpox wheels and smoke box face flying pumps.

    What's interesting about this one is the tender text, it's clearly not white, not even dirty white. Best guess is that it is red which I've not heard of before, except in diesel days when some SD's had red hood side lettering. Some AC's were painted with a red lead cab roof and grey boilers, though these were primarily for passenger runs and not used in the mountains, would need to check my notes as to which batch those were, but I do know they weren't AC-12's. Flag stick holders mounted vertically.

    Tender design change yet again, to the modern slab sided high capacity versions, still pressurised and heated.

    SP 4275.jpg

    No date or location given.

    Lot's of good info on this site. Germane to the current discussion, it looks like SP didn't have FT's, although the Cotton Belt subsidiary did receive five sets in 1944. SP themselves got F3's starting in 1947. I have no idea if the Cotton Belt units would have spent enough time on the SP system, and in the right locations, to mix with the cab forwards.

    The Utahrails site also often has good info on western roads.

    Hi Mick, All,
    Great photos and I'm glad you liked my old models, thanks! I didn't realise how rare such models as the AM-2 were but I did get a very good price for it, I must say. It went to a guy in Australia several years ago now.
    Sadly, I don't really have the resources to model UK, US and EU in 0 scale so H0 is sufficient for me.

    Anyway, IIRC SP's Bloody Nose scheme was introduced in 1958 so a bit too late to run alongside steam really but there's always modellers licence, perhaps?
    Do you follow Tony Thompsons blog by any chance? He's a very good SP modeller whose posts are very entertaining and informative.

    According to J A Strapac's Cotton Belt locomotives the Cotton Belt FT's did not stray very far from their own system.

    Quick interrupt to remind you all about the Winchester Meet next Saturday 20th Oct. Dan Beresford has Piedmont Blues there and I've had another go round the garage with a broom to fill my biscuit tin with bits and pieces. How'd that RS1 get in the dust-pan? Hope to see you there and yes it used to take me a long time to get down there when I lived in Morecambe.

    Managed to scan a few more SP photos in.

    Carrying on with the cab forwards, not a great picture, only postcard size but it is an AC-1 :thumbs:

    SP 4006.jpg

    No date or location is given, but I know it's Dunsmuir CA and I'd hazard it's prewar. Dunsmuir is on my bucket list along with the Shasta route, hopefully next year but it's a long way north of Cajon. The shed in the background was called the Mallet shed, it still stood last year, but there was talk of UP pulling it down as the cladding is asbestos laden corrugation sheets, not steel.

    Something smaller. Consolidation class C10.

    SP 2832.jpg

    Next up a couple of Mountains (MT), both MT-3 class.

    4430, Roseville CA 1955.
    SP 4330.jpg

    4342, San Francisco CA 1950.
    SP 4342.jpg

    Both engines have skyline casings, they were not originally fitted with them and both engines are unique in having Boxpox disc wheels on the main driver. Other engines in the class also received disc drivers, but these were universal type and differed in hole size and placements.

    Next up Northern class or in SP terms, the Golden State class (GS), GS-1

    4402 at Oakland CA 1955
    SP 4402.jpg

    Last up Santa Fe class engines, SP listed these as F class.
