That’s pretty cool.
Interesting design of the cars, which have no end bulkheads, share their trucks, and bridge their gaps for an excavator to run the whole length.
You saw that too? No bulkheads. I thought that was a pretty big gamble to play with their slot machine. 
And I miss placed the video I saw, but believe BNSF or UP is at least running a test train of all aluminum cars with bulkheads but I think I noted the (talgo trucks?) shared between cars. Less weight per car = more coal tonnage.And they’ve already shown the idea will work with the ribbon rail trains.
Big thing I saw in the first video of the work train was the last car had a control shack on it.
OMGram…I need to dig it back out …the headlight ditchlites and Nathan horns are over the top!
I’ll see you in about 2 weeks Hollywood.
Not for EBT Reunion but only so I can punch you in the face!
Looks like we’ll get to see more of your Hi-Rail truck pulling freight cars soon. 
Opps, I thought that was portaloo. 
Wondered why the steel mesh over the windows…
