which are disposed above the tread 18. One-half of the
area moment of the cross section of the rail lies above
the horizontal line B—B passing through the tread 18
and one-half lies below the line B—B. The rail is also
so dimensioned as by making the leg 13 wider than the
leg 12 so that one-half of the area moment of the cross
section of the rail is disposed on one side of the vertical

the rail free to de?ect downwardly upon the imposition
of a load thereon.
An elongate rib 116 integral with the base extends up
wardly between the legs 12 and 13 and has an elongate
tread or load bearing surface 18 which may be engaged
by the beveled annular surface 19* of a railway wheel 20
as the latter rolls along the rail, thereby to support the
wheel and the railway vehicle on which the wheel is
mounted. The rib has an arcuate rounded edge 21 in

It will further be noted that the tread extends along a

It will further be seen that due to the placement of ‘the

ing outwardly extending ?anges whereby one-half of the
mass of the rail is disposed above the tread land the other
one-half of the mass of the rail is disposed below the
tread, one-half of the area moment of the cross section
being disposed to one side of the tread and the other one
half of the mass of the rail being disposed to the other
side of the tread, the center of gravity of any cross section
of said rail being disposed at the tread.
3. A rail including: an elongate horizontal base having
therealong, said rib being disposed parallel and spaced to
tending longitudinally centrally of said rail, said legs
having outwardly extending ?anges disposed above said
tread, the center of gravity of said rail lying on said
