Obviously i can't take video footage when both of us are under heavy haul (working the life out of the engines with the prime movers engaged in low range gears), but enough people were out there taking photos of the multi-combination trailer train, and i'm sure they were taking video too.
The video is bound to turn up on the internet at some point in time, but the next time we have twin prime movers out there under heavy haul contract, i'll be sure to have a video camera strapped to the back of my bicycle helmet.
This is what the rear of my own multi-combination 6 trailer train looks like. Unfortunately you can only see the last 4 trailers:
10 trailers in tow is going to look epic on video.
