What will be interesting is that Amtrak is soliciting bids to replace Amfleet1 and Metroliner club cars. The bids are due by March of 2019? The choices are Briteline type of coaches or Viewliner coaches. Once that choice is made, there maybe a market push to make Viewliner sets as now there are prototypes for:
baggage
Diner
Sleeper
and the American View" Observation/ Inspection" car
