Cooper E80 Loading
Cooper E80 Loading
(OP)
Hi,All
I'm trying to determine wheather 8kip/ft (Cars) is based on single stack or double stack. If it is single stack, what additional load is needed to accomodate double stack?
Thank you all.

Typical Cooper E80 consists of 2 engines and cars (8kip/ft, where continers sit on). I wanted to know how 8 kip/ft was established. Is 8kip/ft based on one container or two containers? or Is 8kip/ft just a design load so it doesn't matter whether a car carries one container or two containers?
Thank you.

The E-80 loading is a conservative historical design established for steam locomotives in 1830. All major railroads use the E-80 design and typically operate double stack.

I don't know the rhyme or reason for the 8k/ft. If you consider the Cooper E80 configuration, it actually works out to be about 10.3k/ft.

The current rating for bridges recommended by AREA is E80, although it represents a very high loading and none of the current car loadings rate as high as E80.
