An SP eastbound has stopped on the eastward double track in front of the Mojave depot. There is not enough time to run to Ansel for the meet. But there is enough time to line a Santa Fe train (Extra 5547 East) down the westward main to East Mojave. Later another train (Extra 5015 East) comes by the station on its way to East Mojave and the connection with the Santa Fe line to Barstow.
