My earlier fortuitous photographic fog-fail was a blessing in disguise.

With an hour to spare before the next eastward Keystone, I drove east toward Gap and at the last minute decide to try for Christiana.

Since Amtrak’s westward Keystone 611 was running late, I figured I’d try to intercept it, and Christiana was a good place to catch morning trains in both directions.

Not long after I arrived at Christiana, the former Metroliner Cab Control car leading 611 came into view, so I made a sequence of it passing.

I began to wonder, what if the next eastbound train doesn’t have Amtrak 621 (the Crayola Blue ACS-64) in the lead?

Then the rail tinged, and a headlight came into view . . .

Crayola Blue!
