MACTRAXX - as the song goes - "those were the days."
The "executive sleeper" was hooked on at NY Penn Station and people could board around like 8 p.m. or so in NYC I believe (for the northbound or southbound trip). Then there was a sleeper for the whole route. And yes, it would be your hotel on wheels. Course with shorter times on the north and south-end of the corridor (originating from NYC), not sure if the Executive sleeper would necessarily be needed any more.
Warrington wanted to make the Twilight Shoreliner (from Newport News to Boston) equivalent to that of the West Coast Coast Starlight. The only problem was that it served Washington DC and Boston largely at unfriendly passenger times. And in terms of onboard services, it started out with good intentions, but then cost cutting took its role.
Many regular NEC riders were up in arms when Warrington proposed to first take take the Viewliners off the NEC schedule during the remaining tenure of his presidency at Amtrak. But then the deept freeze winter of 2005/2006 hit. This took the Viewliner sleepers off the corridor, to cover other routes where Viewliners were despartely needed and had more revenue to generate. A major "Viewliner freeze up" was at hand. The Cardinal was running without its lone Viewliner as well as the Boston section of the Lake Shore Limited. The Viewliner cars had to be rotated down to Miami to get "thawed out." Course many believe the problem could have been averted if the cars were not depleted of HEP during the layover either at Sunnyside or Chicago - to keep them semi-warm etc.
Gunn put the Viewliners through a maintenance program that I think winterized most of them, or at least better than what they had been under Warrington's adminstration.
But with all the Viewliners now back in service, could the NEC put a sleeping car back on Regional #66/67, even though it would probably be the shortest trip a Viewliner would endure? I think the answer is yes and needed. Eventually the car would have to rotate down to Miami, but engine changes at Washington DC for the Silver Service trains could switch Viewliners in/out as needed at their terminus in DC (just run the overnight route on the NEC). Furthermore, could day rooms be had in running the Viewliners from Boston or Washington DC back to Sunnyside etc. for rotation etc. Would be an interesting service, but travelers would finally get compartments that are not offered on the Acela Express - or other high speed trains in the world (even though the Viewliners have their speed restrictions).
I have given up in trying to figure out the current Viewliner utilization. And more Viewliners could be made available if Amtrak tweaked some schedules, or turned some Viewliners in Washington DC (for passengers travelling on the Silver Service south of Washington DC).
Removing the Heritage Crew cars only made capacity worse, and revenue more limiting.
