Note that Amtrak wants a bolt-on nose of some sort for the long distance version. I always suspected that the original design would prove difficult and expensive to repair after the inevitable grade crossing collisions.

The failure breakdown was interesting. 'loading problems'? What the hell does that mean? More importantly, what is Siemens doing to fix this?

Interesting, the ever-maligned 'computer' seems to be more reliable than the radio. I'm not sure how you make a radio unreliable. The new locomotives one will be 'clean'. Good thing, I don't think congtree would like a radio that talks dirty :)

So Amtrak's LD order will be Siemens. No surprise there.

What is a surprise is they're looking at EMUs for...something? The (NE/Keystone) Corridor? Since when was Amtrak that forward-thinking?

Please, anyone at Amtrak reading this, don't call the new Acela replacements 'Acela 21". There's gotta be something better than that lame name.

(I remember when Acela was 'American Flyer", that was a dodged bullet - Lionel was always cooler ;) )

If Amtrak orders any MUs, my suggestion to them as well as partnering states would be to have the MUs run on the Keystones-electric ones of course. For the Springfield Line, run them on the shuttles, obviously under diesel power.

Loading problems means that the Engine does not respond to throttle movements. It's a more common problem them you'd think.

It's my understanding that "loading problems" mean the traction motors will not accept significant amounts of amps from the alternator. In earlier days it was more related to transition, now it seems to be related to computers controlling the flow of electrons to motors.

This is all very lay-person and I understand Nasadowsk is a real live electrics guy of some sort.
