Here's a good sample of trains questionably delayed by NS between Porter and Chicago:
PERE MARQUETTE 371 by CP 482 8:04, arrived CHI 10:27 (due 9:08)
LAKE SHORE LIMITED 49 by CP 482 8:33, arrived CHI 10:42 (due 9:50)
WOLVERINE 351 by CP 482 9:21, arrived CHI 10:52 (due 10:47)
CAPITOL LIMITED 29 left South Bend at 8:07 ET and arrived CHI 10:14 CT (due 8:45 CT) (normally an 85-95 min trip)
BLUE WATER 365 left New Buffalo 11:38 ET and arrived CHI 12:39 CT (due 11:45 CT) (normally a 70-80 min trip)
With 482-CHI running time normally 50-60 min and considering normal times from SB and NBU, the first 4 trains should have been early or OT and 365 only a few min LT.
It should also be noted that 351 made its first OT departure from Kalamazoo in at least 1.5 yr, passed 482 5 min early, only to be tripped up on its final lap. So much for protecting a daily scheduled train's time slot.
WOLVERINE 353 left New Buffalo at 1:36 ET and arrived CHI 2:12 (due 2:32 CT), which indicates the congestion only affected morning trains.
