No, the 125 group restored it from a static exhibit to full working order (not as a mainline loco, just as a heritage railway loco). They did one hell of a job on it & a huge amount of work!
I'm a member of the 125 group & I read the updates of the work carried out. They've also restored some Mk3 loco hauled coaches to work with it (41001 uses a standard loco ETH, as far as I know, not the 415v 3phase AC ETS used by production HSTs). Huge amount of work, carried out by dedicated volunteers.
41001 still sounds great - I heard that valenta scream when it visited the Bo'ness & Kinniel railway a few years ago..
