|Diesel loco #503 holds a unique position on the Green Bay
Route roster, since there were actually two different Alco FA-1s with
that same number.
Most all sources (if not all of them) say GB&W 503 was delivered
in 12/1947, along with KGB&W 501 and KGB&W 502. So the original
FA-1 roster was:
- KGB&W 501
- KGB&W 502
- GB&W 503
In 4/1949, two more FA-1s were added, KGB&W 503 and GB&W 507.
At that time GB&W 503 was renumbered to GB&W 506 to avoid
duplicate numbers. So the roster at that time was:
- KGB&W 501 (1947)
KGB&W 502 (1947)
- GB&W 506 (1947) � ex GBW 503
- KGB&W 503
- GB&W 507 (1949)
What seems puzzling is that a list the builders photo
at left is of 503-507 Logically, this should be a photo of KGB&W 503 and
GB&W 507, built in 1949.
Both 503 and 507 in this photo are lettered for GB&W �
should have been a KGB&W locomotive!
So that raises a couple of questions:
1. Is the image at left actually a builders photo? Does anyone
have a copy where they can verify the numbers on the locos? (The one on
the right looks like 507, but the one on the left looks a little fuzzy.)
Is it from the second set of FA-1 engines built in 1949?
2. In 1949, was a loco delivered as GB&W 503(2)? And then
renumbered as KGB&W 503 while at the same time the original
GB&W 503(1) renumbered to GB&W 506? This seems like a lot of redundant
work, even for a railroad.
