Just saw a Network Rail test train go over the bridge southbound, top
and tailed with a pair of class 37s. Not sure if they came up the
incline from City Thameslink. Probably was quite a loud event if they
did, pity I missed it.

They reversed at Blackfriars; the route (IIRC but ICBW) was Selhurst -
Blackfriars (went to Victoria instead as the paperwork for allowing
37/6s across the bridge had not been approved, allegedly) - Hayes -
Blackfriars - Cannon Street- Blackfriars - Clapham Junction -
Blackfriars - Tulse Hill - Clapham Junction - Kensington Olympia -
Clapham Jn - Selhurst. Made for some interesting pix in the Cannon
Street - Blackfriars area. AFIAA, only 33s and 73s are allowed through
the Thameslink tunnels and beyond as far as Kentish Town.

Whats the reason for the restriction , is it loading gauge or
gradiants or something else entirely?

Height of the tunnels?

ISTR it's carriage length, because of the sharp curve around St Pancras.

If I recall right, there were only certain class 31s allowed to haul the
trains through hotel curve to Kings Cross for a similar reason.

Aren't the Thameslink carriages curved in at each end to go around St
Pancras?

Surely the clearances arn't *that* tight? Besides , didn't they
extensively rebuild that part of the tunnel in the last few years?
Perhaps they improved the clearances while they were at it and these
restrictions no longer apply.

No more than countless similar carriages on the rest of the network.

to go around St Pancras?

Umm, on a curve, it's the *middle* of the carriage that comes closest to
the tunnel walls, not the ends.
