    A simple question,which will denote my ignorance on the subject: please be patient!
    Was only one B unit used in the average lash-up ( A+B+A) or did more than one B unit ( A+B+B+A) get added at times?
    In other words, did I buy one unit too much for my Santa Fe roster?
    Thank you.

    The santa fe railroad had 28 PA1's & 16 PB1's. I have seen them lashed up with 2 PA1's and 2 PB1's units on tv when they would air about railroads awhile back.

    All the pics I've seen on the Fallen Flags site(http://www.rr-fallenflags.org). looks like the Santa Fe ran the PA in only A+B+A.
    If I remember reading somewhere, the Santa Fe actually considered the A+B+A lash-up as one unit. The "B" unit would be numbered as a(ex: 51A).
    But since its your railroad, I'm sure you can come up with a good story as why there is an extra "B" unit. (The two A units scrapped, keeping the B unit..especially if its a different number, though I think the Santa Fe would renumber it 51B)

    Thank you: so basically I should use the A+B+A configuration, or make up some story if I want to use the A+B+B+A configuration.
    I guess I will use the prototypical configuration.
    I will have plenty of "errors" on my layout, owing to ignorance, so I would like to avoid what I now know to be wrong .
    I will use the " hey it is my layout " formula as a last resort...

    Important!

    Not all roads used B units.

    The NKP had probably the 2nd most famous PAs....and despite multiple offerings of NKP B-units, the road never had any. So check your road before buying. The NKP used a single A unit for their St. Louis trains and a pair for their Buffalo-Chicago trains.

    All 4 surviving PA-1s are A units. They started out as AT&SF power...went to the DL&W, and then off to Mexico. 2 are still in Mexico...and Doyle McCormick repatriated the other two. One is going to the Smithsonian painted up for its original railroad, the AT&SF. The one that Doyle is keeping is lettered up for the NKP.

    The units went to the Delaware & Hudson after the Santa Fe, not the Lackawanna. The DL&W never rostered any Alco cab units.

    The 190 still has a long way to go before being complete and only then will Doyle finally start on the Smithsonian's unit. It has come a long way since I last saw it, but still isn't near being finished.

    I've seen that shot before and I loved it. I've seen consists of 4 E-units on many roads (even 5 on the UP), but this was the first time I saw 4 PA/PBs.
