Is Molley The Runt Of The Litter?

I don’t know what the collective noun is for tunnel boring machines. But if it is litter, then surely Molley is the runt. According to this article in Construction Index she is the smallest machine used in the construction of Crossrail.

TBM Molley will build a new Thames Water sewer in west London. She is just 1.45m in diameter and 3.3m long. The main TBMs digging the train tunnels, by contrast, are 7.1m diameter and 150m long. Molley is too small to carry workers on board so is controlled remotely from the surface.

Molley is being used to build a new sewer, as the current one will be in the way of construction works for the tracks.
