Rich,
 
Hope this helps...................
 
I can't speak directly for how it operated under the Q as I didnt start 
until '73. But I dont think the business changed under BN. Feeders generally 
moved in fall and early winter off the high plains to feed lots and farms in the 
east to be fattened. They could come east on GN and NP to the Twin 
Cities or the Q to Galesburg and then North to Savanna if headed for a 
final destination on the C&I. At Savanna I witnessed feeders arriving in 
trains from the North being both spotted at the Savanna stock yard with trucks 
backing up to the pens and also cars of stock coming off the 
eastbounders and being placed in the eastbound local for final spotting at 
points on the C&I. I spotted cars at both Polo and Milledgeville  on 
the eastbound local before the RR got out of the business. We were still 
handling a small but steady business of feeders into the Montgomery yards for 
the brokers there. 
 
This would be the general pattern for any stock or shipment. Get it as 
close to destination on the through train and then give it to the local for 
delivery.
 
From what the old timers told me the local rail handled Chicago stock yard 
business pattern was to spot mtys on the westbound local. Then depending on 
volume either the eastbound local or a stock extra picked them up for movement 
to Chicago. Checking the old ETTs notations shows a stock pick up extra leaving 
Galesburg every Monday,Weds and Thurs to p/u stock between GT and Mendota as 
late as ETT #31 dated 9/24/50  
 
The picture of the westbound load of stock at Mendota in last years BRHS 
calendar is the one I'd really like to research to learn more about.
