Todd,

Rudnick lists the last series of UP built cars 920-969 as 27 foot, 28,000 lb. capacity cars; the Peninsular 30 foot cars are listed as 40,000 lb. capacity cars.

Maxwell's roster in The Pictorial Supplement . . .  lists only the post 1885 numbers, but all 14 ton (28,000 lb capacity) cars are listed as 27 foot cars.

Ferrell's recent roster in The South Park Line omits the 920-969 series all together.

I've come to think of car lengths of the inherited cars in terms of the capacity of the underlying trucks:

Litchfield, "type-A", 12 ton trucks were generally used under 26 foot cars.
UP style, "type-C", 14 ton trucks generally under 27 foot cars.
Penisnuslar, "type-B", 20 ton trucks under the 30 foot Peninsular cars.

But as McCoy might say "Dammit Jim, I'm a doctor, not a freight car specialist!"

Perhaps Ron Rudnick could weigh in here.
