The first two units an A and a B were released for test from Schenectady on June 26, 1946. Units were tested on the Lehigh Valley then returned to Schenectady for work before sale to Santa Fe in September 1946. Data is from Richard Steinbrenner's The American Locomotive Company A Centennial Remembrance --SSW9389 23:26, 19 November 2005 (UTC)
American Freedom Train PA-1 #1776 operated from September 17, 1947 to January 1949. Unit was sold to GM&O as their #292. From Steinbrenner's book. --SSW9389 23:26, 19 November 2005 (UTC)
The last two PA-1s built in 12/49 were painted in CN paint #9077-9078, demonstrated in Canada from 2/50-5/50, were returned to Alco, rebuilt as PA-2s and sold to MKT! Steinbrenner p.274. --SSW9389 23:39, 19 November 2005 (UTC)
Three PA-2s were exported in 1953 to Brazil's Paulista Railway #500-502. Several are still extant at this time! Steinbrenner p. 308. --SSW9389 23:39, 19 November 2005 (UTC)
Steinbrenner has several notes on the PA nose design and its likely relationship with the Fairbanks-Morse Erie Built locomotive. Steinbrenner credits the industrial designer Raymond Loewy with credit for both. Steinbrenner p. 249. --SSW9389 23:53, 19 November 2005 (UTC)
One "major" book might be Andy Romano's PA: Alco's Glamour Girl, assuming it can be found. I think Jim Boyd had a hand in another book whose title escapes me---maybe Alco Passenger Diesels---but it deals with almost every group of PA/PBs bought by a railroad.--Foxhound 16:52, 21 December 2005 (UTC)
That "major" book has now been added. -- MakeChooChooGoNow 18:03, 27 August 2006 (UTC)
[edit] PA and PB-3????
The designation PA / PB-3 was for the never built 2400 hp version with the 251 engine.
All 2250 hp PA´s were named PA-2 (or PB-2), sometimes railfans call the later -2´s as -3 but thats not official.
As example Southern Pacifics locomotive classes DP-9 and DP-10.
DP-9: Built in April 1952, numbers #6023-6027 (PA) and #5920+5921 (PB). ·Equipped with the 244F diesel with aircooled turbocharger. ·Equipped WITH the rounded grille work directly behind the cab, looks like an PA-1! The other SP PA/PB-2 with the PA-1 design is the class DP-8, built August-September, 1950, #6019-6022 (PA) and #5918+5919 (PB).
DP-10: Built between May and July 1953, numbers #6028-6033 (PA) and #5922-5924 (PB) ·Equipped with the 244G diesel with watercooled turbocharger. So the stack was turned 90 degrees to the F-version. ·These units were also equipped with nose mounted MU receptacles. ·Delivered without a pilot, upon delivery SP´s Sacramento shop installed also an SP built pilot / snowplow. ·NOT equipped with the rounded grille work directly behind the cab and the portholes behind the shutters.
In September/October 1953 the SP got the last series of PA´s, design similar to the DP-10, only 12 cab units, class DP-11, #6034-6045
All four classes DP-8 to DP-11, were named as PA/PB-2 by SP and others. The third DP-10 B-unit #5924 was named as the last built PB-2.
If the designation PA/PB-3 would be correct, the DP-9 were PA/PB-2 and the DP-10 were PA/PB-3 but both were PA/PB-2.
SP PA units with numbers between 6055 and 6066 were the 12 former T&NO PA-1´s, with the number 6067 and 6068 the two former Cotton Belt (SSW) PA-1´s. The two SSW´s PA-1 make sometimes confusion because their class is the higher DP-13 but the T&NO units are the low class DP-6, thats because they were built together with SP´s PA-1´s #6011-6016, class DP-6, and were identical to them. The oldest PA-1´s were class DP-5, #6005-6010. But there was never a PA-3 /PB-3 listet.
Under "External Links" is the link to Dieselshop. There are only PA-1´s & PB-1´s and PA-2´s & PB-2´s listed, no PA-3 or PB-3
The "new" original buyers paragraph accounts for 303 units when only 297 were built. I think we were better off with the roster that we had previously. Also two railroads that owned PAs are not mentioned at all those two roads being the St. Louis Southwestern and the Pittsburg & Lake Erie. --SSW9389 12:59, 2 June 2007 (UTC)
Pittsburgh & Lake Erie sublettered units are New York Central PA-1s # 4204-4207 and New York Central PA-2s #4213-4214. --SSW9389 (talk) 19:49, 27 May 2008 (UTC)
The PA-2 PB2 demonstrators were built for General Electric's "More Power to America" Train. The units were sold to New York Central #4212 & #4308 after a 15-month cross country tour. Data from Steinbrenner p.307.
While it is true that the Cotton Belt and Texas & New Orleans units were built concurrently by ALCO, they are not identical because the Cotton Belt units lacked dynamic brakes. The Cotton Belt units were leased to the Southern Pacific in December 1959 after all Cotton Belt passenger service ceased on November 30, 1959. --SSW9389 (talk) 15:50, 12 January 2008 (UTC)
