Thanks, Jim. I've made an effort at transcribing the lyrics myself (not all that difficult). THe lead guitar seem to be a "three-chord trick" in D-major.

Here goes:

Well, the greatest train that ever ran down America's railway tracks
Was the Orange Blossom Special, bringing my baby back
From New York to Miami you could hear those drivers roll
And the Orange Blossom Special don't stop in Waldo anymore

Well, people would line the railroad track to watch the OBS go by.
It made grown men shiver, and little babies cry
It shook the ground for miles around, fifty years ago
And the Orange Blossom Special don't stop in Clearwater no more

Well, just tonight for old time sake, we're gonna make the engine one
Bring the Orange Blossom Special right down the Clearwater line
Elan he is the engineer, Raiford is the light
And the Orange Blossom Special shines in Clearwater tonight
