Sure, there's a romance to riding the rails. And the technology, though pushing the two century mark, is still fascinating. (No, I don't like being stopped by a train anymore than the next guy.)
There's something about the way the engine provides power (motive force, if you will) which is transmitted link by link to the very end of the train, perhaps a mile back. No matter which direction the engine is going, uphill or down, the very last car (enter a plaintive lament for the extinct caboose) will follow. Indeed there's a fascinating place in the Canadian Rockies where the locomotives emerge from a mountain tunnel directly below and perpendicular to their rear cars as they navigate the famous Spiral Tunnel.
But of course the cars must stay connected to one another if that magnificent train is going to remain a unit and deliver its full load. How sad when we stop looking for ways to get along and break the links that bind us together. Our divorce culture has permeated every aspect of life, wreaking its full havoc wherever it is found. And God hates it. (Mal. 2:16).
