Technically, the train could have a same-day turnaround in LAX on Wednesday and Friday.The impression I got from a conversation with the Director of National Operations is that normally it will be a same day turn around at LAX and overnight turn around in NOL. But as usual, with everything, what really happens is the final arbiter in these things. So we will just have to wait and see.
However, with the change in days of operations (which enables all the cost savings and the equipment set to be freed up in NOL), you'll have a train leaving LAX on Sunday, but the inbound equipment won't get in until Monday.
So, whether they do a same-day turn around on Wednesday and Friday, and hold the Monday arrival as a spare all week until the Sunday departure, or whether they have the two-day turnaround for each set, makes no real difference in the end as far as equipment utilization and availability goes.
My bet is that both will happen, depending on the needs of the specific equipment on the specific day/week.
