Surely it can be done at night? Besides , how many people does a slow
moving
low loader inconvenience , especially if its doing 20mph on windy B
road?

You would have thought so - but there are many other factors to take into
consideration also (especially for overnight journeys). For example, train
planning would be involved, in order to roster crews, locomotives and
prepare paths for the movement; the issue (especially overnight) of
engineering work and whether or not signalling centres are open for the
required route (quite a few routes have no overnight cover any more) comes
into the equation. The cost of preparing a train plan and implementing it
may well have made the quoted price to LUL unacceptable and it is far easier
to contract Allelys (or whoever) to do the work. For most of the journeys
major roads and motorways are used for transportation and smaller roads are
only used at the extreme ends of the journey - there is no cost to the
haulier (unless a police escort is required and charged for) for
inconveniencing motorists, whereas Network Rail and the FOCs would factor
such inconvenience into their costs.

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.
