I suspect the actual claim concerns the loading gauge not the volume
of any vehicle.

They can't, the limits are 18.75m length, 4.2m height (for some reason
the Eurotunnel page "Safety and Security - Vehicle restrictions"
doesn't mention width) and 44 tonnes weight; larger vehicles are
permitted on roads subject when required to the laws applicable to
"abnormal loads". IIRC these dimensions will prevent many vehicles
using the tunnel on grounds of height which are not "abnormal".

Does anyone know how long, end to end, that railway, or tramroad was?
In other words how far did the Pioneer travel making a single journey?

Correct! And it still is - NASA now use it for moving the
Orbiters from the VAB to the launch pad...

It's an extraordinary piece of machinery seen up close...
