At 20:01 on February 1, BNSF suffered another remote control derailment,
this time in the Tulsa yards. The remote yard job sideswiped their lead
locomotive, BNSF SD39 6212, into the rear two locomotives of the
H-TULBAR1-01, the 4735 & 872. All were derailed, but upright. The main
tracks were not affected. The two receiving and departure tracks were
back in service by 7:00 the next morning. The cause was under
investigation.
