A work train at Lakepoint parked this eastbound, and two Westbound. Allowing me the opportunity get into positions to catch all three train. When the work train cleared. The LUE46 local with SD70M's 3917 and 3889 are at Erda were they waited for the two westbound's to pass. From Erda they were able to make it to Garfield, where the crew went dead, and a van was there retrieve them, and bring a new crew to get the train back to Roper yard.
