Ok why does everyone hate amtrak's horizon coaches. to me on the inside they look the same as the amfleets and they ride the same. at least to me. whats the big deal.
Well, unlike the Amfleets... the Horizons are boxes, big flat boxes.Micah's points are all true, but he has left out their high speed stability issues. Much above 90 mph, the GSC trucks, which are not optimized for the Comet body characteristics (they are designed for inboard bearing trucks) the cars start to pitch around their longitudinal axis and while no derailments have ever, thank god, occurred, their have been instances where wheels have fully lifted off the ground at speeds of 110 and over. Amtrak restricts the cars, which are rated for 125 for reasons unknown, to 90 mph.
Don't know where you get info from but Horizons are not restricted to 90 mph, the timetable speed for Horizons 51000 - 54599 and 58000 - 58109 are 125 mph as per Amtrak timetable rule 37-S5 on page 287 on NEC timetableMicah's points are all true, but he has left out their high speed stability issues.

They pop up every now and again.Interesting. I haven't seen any horizon coach discussions. You learn something new everyday.
Yes, Amtrak converted the Horizon BC cars to mimic what they did with the Amfleet Club-Dinette cars. They had enough seats left over from the old Metroliner FC cars, so they invested in the upgrades to the Horizons after they finished with the Amfleets.My lone Horizon ride (Kalamazoo-Ann Arbor) was quite comfortable. I paid the $12 Business Class upgrade fee and ended up in 1-2 seating behind the cafe car with about three other people. Though the Coaches I walked through did look pretty cramped and dirty.
Another issue with most Amtrak single level coaches is that the windows are fairly high, and this restricts viewing of the passing scene. This dilutes one of Amtrak's major advantages. I'm reasonably tall but I still notice this, and it must be more significant for shorter people.Yes, Amtrak converted the Horizon BC cars to mimic what they did with the Amfleet Club-Dinette cars.

That's not what I have been informed of by various Amtrak managers. Tell me, Dutch, where have you seen a Horizon doing more then 90?Don't know where you get info from but Horizons are not restricted to 90 mph, the timetable speed for Horizons 51000 - 54599 and 58000 - 58109 are 125 mph as per Amtrak timetable rule 37-S5 on page 287 on NEC timetableMicah's points are all true, but he has left out their high speed stability issues.

only restriction is cars in series 53000 & 58000 are restricted from Third rail territory with exception to cars 53501, 53505, 53509, 53510, & 53511.
Okay, good point about the operating environment.Airplanes don't spend their time being buffetted by dirty, sand, and rocks.
Also, the Horizon is a smaller car then the amfleet. Shorter and narrower.
I have seen Horizons subbing for AF II lounges on the Silvers in Virginia. I suppose they could have slowed the train down by 15-20 mph for the NEC run, but that doesn't seem terribly likely.That's not what I have been informed of by various Amtrak managers.

I don't have my spec book with me, but I think the Amfleet is actually 10'8" wide at its widest point because of the curvature.
