Locomotives in front vs. back of a consist.

Hi All: I understand the 3 track main in Nebraska gets its share of Coal unit trains..I can just see those big babies rolling out of Powder River Basin..Not to change the subject to far, but I was reading the other day about the new Kate Shelly bridge..They built the New one right next to it(can handle 70MPH were the old one was down to 25MPH)..Those of you that don't know the Story, She saved a train from Disaster back in the late 1800's..And so the bridge was named after her.
Their going to keep the old one intact for historical value..This all happened on the Des Moines, Iowa River outside of Boone, Iowa..

PS. That bridge also carries alot of Unit Trains mainly UP..

Push-pull services (loco at one end and a driving trailer at the other) are not uncommon in the UK.

On the East Coast Main Line many of the services are run using 125mph push-pull sets with a class 91 electric locomotive at the London end and a driving van trailer (DVT) at the other.

Perhaps the most unusual example in the UK in recent years was the old BR Advanced Passenger Train (ATP-P), which had two powercars (without cabs) in the middle of a 14 car rake, with driving trailers at either end.
