Santiago - Nice purchase, of the Poage "H" wheeled water column. Not universal across the Burlington, but sufficiently represented to characterize a number of Burlington locales. In Four ways West's "Burlington Route Passenger Trains - Vol Two", on p.49, just such a column is beautifully pictured, in a Neal Miller photo, next to the eastbound Denver Zephyr in Fort Morgan, CO, pulled by shovel nose (pre E5's) "motors", at sunset, 11-03-47. The same water column was seen at the Galesburg engine facilities, at the mainline coaling tower in Mendota, IL, and at the Centralia, IL engine facilities. I am sure other locations, too, with out doing research.
Phil McC - think the Burlington held the speed crown in mid to late 1950's with their Twin Cities Zephyrs, in Trains Magazine speed survey conducted by Don Steffee.
