Paul,
In reply to your statement when was the last hump yard built: UP has plans drawn already and is waiting for local government approval, to build a 44 track mini-hump yard in Red Rocks, Arizona (West of Tucson). Construction could start later this year. So the hump yard isn't dead yet.

Bill and List,

There is plenty of bunching in the current system. In the Trains examples,
48 to 88 hours elapsed between the time the car was released by the shipper,
and the time the car departed the regional class yard at Spring TX, 23 miles
north of Houston. In other words, an average of 3 days of production was
"bunched" on about 45 route-miles of track, with presumably an equivalent
inventory of returning empties.
"From a facility standpoint, most
hump yards are not designed to efficiently pass blocks of cars."
The idea is to get rid of hump yards altogether. Portions of some hump yards
will need to be retained to consolidate and seperate groups of "minitrains",
but the humps themselves will be gone. The marketplace has already decided
the hump yard is obsolete. When was the last one built? How many are being
planned? The last flurry of hump yard construction occurred in the 1970's.
Northtown and Spokane on BN, Barstow on ATSF, Sheffield and Linwood on SR. I
think Queensgate in Cincinnati was early 80's, and UP built a "mini-hump" in
Louisiana in the early 90's. The last hump in the Northeast was Buckeye near
Columbus, opened by PC in 1969, 38 years ago.
Getting back to EL, I believe Steve has a file that concerns a solicitation
for a steel move in Ohio, proposing EL as an alternative to truck. It was
the kind of short-haul move the RR's no longer seek, but was instructive
nonetheless. Steve, can you share that with us?
