Why take a 170ton new special tamping machine all the way from Linz in
Austria by rail to catch a ferry all the way to Immingham, and with the
eventual destination London - take it by road from Immingham to London?
Why could not have gone by rail, instead of causing chaos on the roads?
Why not deliver it closer to London directly?
That is the usual reason why such kit has to be moved by road.
Like the Shinkansen going to the York railway museum.
Incidentally what is the limit these days on wide vehicles travelling on
motorways and trunk roads before they have to have a "wide load" escort
vehicle in attendance. I saw one recently that was significantly wider
than a single motorway lane and the only concessions were red/yellow
triangles on its bottom rear corners.
It was blocking two lanes as it trundled along the A1(M)at under 50mph.
Oversized portacabin at least 1.5m wider than a single motorway lane
(which ISTR is about 3.6m).
I seem to remember seeing at York railway museum different rail
heights/cross sections for high speed trains From memory the rail that
the Shinkansen run on was 2x to 3x the height of the standard British
track so perhaps the wheels would bottom out on the sleepers or ballast
on the UK track
I'm not sure what you were asking there, but from what I gathered...
It was a 170 ton rail tamper intended for Network Rail, in two
sections. It had already travelled 700 (?) miles by rail from Linz to
the channel ferry port. It was loaded onto a road transport at the
ferry port, then onto the ferry to Immingham, off the ferry then by
road all the way to west London. No doubt
It depends upon which lines it is to be used. Lines have different
loading gauges depending upon when they were built and by which company
and different permissible axle loadings depending upon the type and
"weight" of rail, bridge limits, etc.
Some lines required steam trains (and later diesels) with cut-down cabs
compared to the same class of locos used on other lines and locos
were/are often prohibited due to their overall weight or axle loads.
All locos and rolling stock have a route availability, which combines
axle loading and loading gauge and informs where they can and cannot be
It may be possible to send an out of gauge loco or train along a line,
but only with accurate measurements beforehand; removal of some
structures that are too close to the track; at slow speed and under
special instruction and supervision.
Generally though, locos, carriages, etc. are transported by road,
because they cannot easily be fitted between the scheduled trains and
because it is cheaper!
