[N&W] Re: "A" Class Locomotive Details

[nw-mailing-list at nwhs.org]

There were two types of aftercoolers used on the "A's". Listed below are the
types and the "A's" that had these aftercoolers.
Westinghouse A-2 type:
1200, 1201, 1208, 1214, 1215, 1217, 1218, 1221, 1224, 1228, 1229, 1231, 1233,
1234 and 1239 .
  Wilson:
1200, 1203, 1204, 1205, 1207, 1222,  1229 and 1232.
Photo's show that 1200 and 1229 had both types, but I'm not sure of the
sequence of this change or if they were really changed. It has been
documented that the front engines were sometimes switched during shopping, so
this is the other possibility.
