They often deadhead equipment as you stated so it can be conveniently added/removed. It keeps them from having to break apart the train later.Why it’s deadheading and not in service is for convenience, with a small chance of something broken that would prevent it been used as a dinner.
We recently rode from New Orleans to New York. There was a new diner on the train for "first class" passengers and one "lead service attendant" in the diner. Who she leading since there were no other employees was not clear. Everything was self service. For some elderly people that was not easy. One sleeping car attendant said he was not going to even offer food service to people's rooms! One the way back, the attendant took orders and delivered the "food bowls," as I call them, to the tables. She asked me not to write a letter complimenting her on the extra effort because she didn't "want to get in trouble." Imagine getting in trouble for providing service! So, now that Amtrak has fired a lot of dining car employees, are diner really coming back? Iffy at best with the current crowd in control.
Well maybe someone with a brain realized that it was impossible to satisfy the needs of an entire single-level LD train with one limited food service car?
On a recent New York/New Orleans trip, the sleepers were at the front of the train, then diner, then cafe. While the car rode OK South of Washington, we were very alarmed at the "wagging" that went on on the Northeast Corridor when the speed was up near 100 mph. The sleeper was literally slamming sideways, back and forth at an alarming enough intensity that I was worried about an accident.The Silver Service and Crescent consists have been running the sleepers in the front for some time now.
Hmmm... Just noticed on the other thread that the sleepers have been moved to the rear on Silver trains. Don't know about the Crescent, but its consists differ slightly because of the Business Class coach.
I thought BC on the Crescent was scrapped. Last time I was on the Crescent it was an AM-2 in front of the sleepers, but I'm pretty sure it isn't there anymore.
