You can hear several recordings at last.fm, but it's very hard to understand. Here's my attempt:

Intro:
My Lord, she blows,
Waa-waa
Get on board,
Better get your ticket now
My Lord, she blows,
Waaaaa-waaaaaa
Waa-waa

Gospel train is comin,
You better get your ticket right
You better set your house in order, friends,
You know the train gonna be here tonight

Don't you hear the whistle blowin'
Hear the bells a-tollin'
Don't you hear the engine exhaustin' friends,
You know the train gonna be here tonight

Now before she enters the Pearly Gates of Heaven,
Can't you imagine that you can hear this train go?
She blows across to (Buffalo???).
You know the train's gonna be here tonight.

[Mouth music]

Ah, sinner man
Don't you be ridin' this train?
You better set your house in order, friend.
You know the train gonna be here tonight.


My Lord, she blows,
Waaaaa-waaaaaa
Waa-waa Waaaaaa


Anybody else want to make a stab? I don't buy that"buffalo" at all, but I don't know what I hear.
What I DO know, is that I really like the Golden Gate Quartet.
