Showing the difference in the short hoods of Alco's C-424
and C-420 engines. .
GB&W #319 (in the foreground) was an Alco C-424,
while #323 was a C-420.
The C-424 had a 16-cylinder 2400 horsepower engine, while the C-420 had a
smaller 12-cylinder 2000 horsepower engine on a similar frame. Hence, the
C-420 had a longer short hood.
The C-424 shown in the photo was an early production unit with the battery
box behind the cab, forming a rear step. The C-420 has roughly the proportions
of the earlier RS-11, but with no notches on the low short hood and only
shallow notches on high hoods.
The photo also shows the difference a faded paint scheme can make.
Besides the paint which is almost turning pink, the GREEN BAY ROUTE
herald is faded out on #319. #323 has a newer paint job -- although it
can't be seen in this photo, it has the new "serif font" large GBW on
the long hood sides.
Both of these units came to the Green Bay Route second-hand: #319 was
originally Pennsylvania Railroad #2415, while #323 started out as Lehigh & Hudson River
#27. They came to the GB&W in 1980.
