Re the C&S 150 series switchers and CBQ U30Bs.

 

Could it be that those switchers were C&S/ATSF switchers?

 

Thanks!

The jump to the 620 series was, as Brian notes, simply because there were not enough available numbers in the high 100s -- only 190-199.  And since FW&D switchers occupied the numbers from 601 through 610, the GP40s were started at 620.  Don't ask me why the Q numbered U30Bs in the 150 series, which conflicted with C&S switchers, but then didn't want a conflict with FW&D switchers.  Obviously, there was little likelihood of either C&S or FW&D switchers being confused with Q road units, but since the Q units were operating though over the C&S-FW&D in the latter half of the 1960s, it was considered wise -- at least by the time the second group of GP40s arrived -- not to create number conflicts.  And the railroad saw no reason to renumber the earlier GP40s into the 620 series, as their numbers from 170-189 didn't cause any conflicts.  The 160s were not used for second generation units because they were still occupied by F-units in the 1960s, and the 200s, 300s, 400s and 500s were all occupied, so the 620 series offered the first available sizable group of open numbers.

Hopefully we have a numbering guru who can make it all clear.

Great info Bob!  My quick review shows that the lower number sequence only had 10 slots above or open and another 20 GP40s wouldn't fit.  I have not confirmed the retirement date of the GP7s vs the arrival dates of the 40's.  Looks like there was plenty of room to renumber the original group with the new arrivals in the 600 series. I don't think the phase difference would have been enough to necessitate separate road number series.

Brian,

 

Re this link, the difference was Phase Ia3 and Phase IIa3:

Is there any difference between the two different number series of GP40's?  Was the any difference in paint schemes?  Am I correct only one of these units got the pre merger scheme?

Thank you,

Brian Durham
