Whenever you guys end up updating the suspension for the Acela, please make the Powercar suspension similar to the Pacer. The cabs notoriously bounce up and down from small imperfections in the rails, and also violently sway from side to side. The front plow will sometimes even hit the rails and spark. Please note that this is for the Powercars ONLY. The coaches should ride smoothly.
I remember riding an acela for the first time and I can definitely relate. It felt like I was gonna fall out of my seat several times and could see the coach sway jerk around quite a bit compared to an acs64. Definitely would like to see this.
