I suspect you saw one of the Robel ROMITAMP mini-tampers (908021-7 or 908020-9) which are used for correcting track geometry. More details on what they do here https://railway-news.com/new-robel-mini-tamping-machine-romitamp-2-0/ .
There has been 1 present at Shettleston of late. If still there Wednesday it will leave you as having seen the other. Lookout for sightseeing
Sightings by other members would imply it's 908021, click here
Neither were on Shettleston today
908021 was there on 6th may though
