Yes , I guess you're right. Does seem a bit silly tho. After all, if
you need to tow a road vehicle somewhere you don't stick it on a train.

Incidentaly , just out of interest , what is the max speed for LUL
stock when being hauled dead by rail?

Ah, good question! It depends very much on the brake that can be applied and
the effectiveness of the translator vehicles, plus (I would imagine) whether
the motors are disconnected or not. I'd be surprised if the maximum speed
was very high. IIRC, when the Met line A stock was taken to Derby for
refurbishment (via Amersham, Aylesbury, High Wycombe, Greenford, Reading,
Didcot, Banbury, Leamington Spa, Solihull and Tamworth - quite a circuitous
route) it was limited to a maximum speed of 40mph and moved on a Saturday,
two sets at a time, to reduce the inconvenience to other traffic. I'll have
to check with a mate of mine who was an Acton driver at the time and took
several of the trains through.
