Boston Marathon, CSX and Framingham

Hey guys, i was reading the Boston Globe and they were syaing back in the day, the marathon used to get split by trains in Framingham and the runners who beat the train kept going and the runners who didn't make it, had to wait.

What does CSX do now? Does Q274 still go to the CP yard or do they wait till all the runners have passed CP 22?

If I remember correctly nothing is allowed down to the CP Yard during the majority of the marathon.... inbound trains are tied-down in Nevins.
