I'm surprised they've ordered an AC only version. Shoegear doesn't add any
significant weight to a train unlike adding a transformer for AC so why not
just spec the whole lot as dual voltage so they can be mixed and matched as
and when?

A guess but I wonder if not speccing dual voltage for the routes out of Liv St is a way of avoiding a whole pile of survey and inspection work and possible rectification work. It is possible that there is equipment in the way or which infringes standards for clearances for shoegear on the lines out of Liv St. It's not really an issue for the NLL route as it was previously third rail so would almost certainly be compliant. I assume that the work on the GOBLIN includes checking for clearances anyway, given track lowering and platform works, so it's not an issue there either.
