Yes I realize that now. I thought you were referring to rolling stock. You referred to the "first set" which could easily have referred to set of equipment.
Will more track work be done? And why start up a train before the work has been done? 35 mph!
Here's a link to the service that survives; there used to be several a day, not just one). Takes nearly seven hours and makes many stops (the former Marplatense train took four and a half hours and made no intermediate stops). I believe the equipment now in service was manufactured in China. There is no longer a dining car but there is a snack car - probably just ham and cheese sandwiches. Why not be adventurous and try it and give us a report?
