So Katie and I are sitting there, watching, waiting. We see the rear locomotive approach the intersection and ... come to a stop. Sigh. After a few minutes, the locomotive pulls away rather quickly and this time there is no train attached. We are both very excited by this.
And the the cross-bars don't go up. The red lights are still flashing and the warning bell is still clanging. We see the cross-bar for the on-coming traffic rise and then stop half way. It hangs there for a minute then drops back down. Shortly, our cross-bar rises half way for a few minutes and then drops back down.
It takes a few of these cycles for us to get close enough to see the source of this mystery. The cross-bars are being directly lifted by (I presume) a train company employee. He lifts one for a few minutes and then cross the street the lift the other.
This is a first; never seen anything like this before.
Twenty minutes of waiting. During rush hour. We had plenty of company.
