Passenger schedules

[NW Mailing List]

I was looking through the J" book and at the route grade profiles and  
I was wondering how the schedules changed from the 1920's and 1930's  
with K1's and K2 pulling the consists to the J's and J1's during WWII  
and then after WWII.  Since the J's were more powerful were they able  
to reduce the times between stops to any significant amount, or did  
they just load up the consist to the max for the engines used?  What  
were the average speeds?  I figure the J's were more powerful when the  
boiler pressure was increased from 275 to 300PSI, but did that imply  
faster, or heavier consists?   Did the K2's get different cylinders  
when they were upgraded?  Were the N&W passenger engines limited by  
speed limits or technical specifications?   I hear stories of J's  
getting past 100MPH, but nothing about the K1's or K2's.   Is their  
any source for finding out their operational specifications, like  
speed, max loads etc?
