TUNNELS.

TiINNELS.

No single Tunnel will exceed
500 yards in length.
GRADIENTS.

For the Traffic from Worcester
to London, there will be a saving
of 5 miles, and the Gradients of
this Line (excepting the Dodes-
well Plane) do not in any case
exceed 16 feet per mile.

Although the Directors' Report is prudently silent
upon the point, the Tring Prospectus states the distance to
be six miles less from Oxford to London.
The actual distances by sections, however, prove,
Oxford by Tring to London
Oxford by Didcot to London ... 62 10

Difference only 1 mile 40 chains.
It may be alleged, perhaps, and truly, that the London
and Birmingham Station, at Euston Grove, is nearer to the
City than the Great Western Station at Paddington,
whence these respective distances are calculated ; but on
the other hand, it is worthy of observation, that the latter
Depot is nearer and more direct both to Piccadilly and
Oxford-street ; and it may be fairly assumed, that as far as
the traffic from Oxford and Cheltenham is concerned,
not being commercial, three-fourths, at least, in number of
Passengers will be destined for the West end of London.
'Phe fares to the City, by public conveyance, are at present
the same from both places.
The several inaccuracies thus enumerated are, however,
trivial indeed, when contrasted with the total suppression of
facts of material value in determining the comparative su-
periority of the two lines.
Admitting the distances to be more or less favourable to
the Tring, the first enquiry is naturally directed to the ge-
neral features of the country to be traversed. What are
the respective summit heights to be attained? This must
be acknowledged at all hands, a principal ingredient in the
comparison, inasmuch as Mr. George Stephenson, and other
Engineers of ability, have proved that twenty feet of verti-
cal rise may be generally esteemed equal to one additional
mile of distance.

The following statements are indisputable, being deduced
from the Parliamentary plans and sections already refer-
red to.

n making the journey from London to Oxford and back
again, the traffic must. therefore overcome 423 feet of verti-
cal rise by the Tring, more than by the Didcot Line,
making an average excess each way of 2111 feet, which is
equal upon Mr. George Stephenson's evidence to an extra
distance of 10i- miles between Oxford and London.
