DE10 Question

[ATShinkansen]

Hello,

 

I've got a question pertaining to the DE10's axle arrangement. Some sources say AAA-B, while others say C-B, with most seeming to agree with the former. If it is indeed AAA-B, how are the first three axles arranged to not make it a C truck? My only guess would be that the center axle is rigidly mounted while the other two pivot around it.

 

Thanks,

So AAA means it's 3 independent axles as opposed to C, which would be 3 on a single fixed frame?  I don't understand those classifications so I never really thought about it.  I figured it just scraped through turns or something.

 

Here's a pretty cool CG image of the DT132A type that shows how it's an AAA configuration:

And the other 3-axle truck that DE10s have is the DT141.  On this page, the third image is one being hoisted and it's not rigid, so I guess this is the same situation:

Thanks for bringing this up, this is an interesting detail.  I'm sure some other members will have some info, too.
