A rail anchor and a rail anchor assembly are provided for use with a concrete railroad tie. An elastomeric plate is placed on a top surface of the railroad tie. A rigid plate is placed on top of the elastomeric plate. The rail anchor is placed adjacent the elastomeric plate and the rigid plate. The rail anchor has a first end with a receiving opening and a second end with a receiving indentation to receive edges of the flanges of the railroad rail. The rail anchor has a center portion joining the two ends. The outer portion of the rail anchor extends downwardly an amount less than the thickness of the elastomeric plate and the rigid plate to avoid contact with the concrete railroad tie.
1. A rail anchor assembly comprising
a concrete railroad tie having a generally rectangular generally flat top surface, an elastomeric plate placed on the top surface of the railroad tie, the elastomeric plate having a flat bottom surface and a flat top surface and two parallel longitudinal edges,
at least one generally rectangular rigid steel plate placed on the top surface of the elastomeric plate, the rigid steel plate having a flat top surface and a flat bottom surface and two parallel longitudinal edges,
a railroad rail having a first flange and a second flange placed on the top surface of the rigid steel plate,
and a one piece rail anchor, the one piece rail anchor comprising a first end bent back to form a receiving opening, a second end having a receiving indentation, and a center portion connecting the first and second ends,
the first end receiving opening receiving an edge portion of the first flange of the railroad rail,
the second end receiving indentation receiving an edge portion of the second flange of the railroad rail,
the one piece rail anchor being positioned adjacent one of the longitudinal edges of the elastomeric plate and adjacent one of the longitudinal edges of the rigid steel plate,
the center portion of the rail anchor arched away from a bottom surface of the rail, and a lowest bottom surface of the center portion extending downwardly an amount less than a vertical extent of the flat bottom surface of the elastomeric plate so as to avoid contact between the rail anchor and the concrete railroad tie.
2. The rail anchor assembly of claim 1
wherein the elastomeric plate is formed of a high density polymer.
3. The rail anchor assembly of claim 1
wherein the one piece rail anchor is formed of a high strength steel.
4. The rail anchor assembly of claim 1
wherein the one piece rail anchor has a generally rectangular cross section.
5. The rail anchor assembly of claim 1
wherein the rail anchor has a generally elongated structure and
wherein a bottom surface of the center portion extends downwardly from the top surface of the rigid plate supporting the railroad rail no more than 1.0 inches (2.5 cm).
6. The rail anchor assembly of claim 1
Wherein an additional rigid steel plate is provided on top of the rigid steel plate.
7. The rail anchor assembly of claim 1
wherein the total thickness of the rigid steel plate and the elastomeric plate is about 1.15 inches (2.9 cm),
and a bottom surface of the center portion of the rail anchor extends about 1.5 inches (3.8 cm) from the top surface of the rigid plate.
8. A rail anchor assembly comprising:
a concrete railroad tie having a generally flat top surface,
a generally rectangular elastomeric plate placed on the top surface of the railroad tie, the elastomeric plate having a flat bottom surface, a flat top surface, and two parallel longitudinal edges,
at least one generally rectangular rigid steel plate placed on the top surface of the elastomeric plate, the rigid steel plate having a flat top surface and two parallel longitudinal edges,
a railroad rail having a first flange and a second flange placed on the top surface of the rigid steel plate,
and a one piece rail anchor, the one piece rail anchor comprised of an elongated steel structure having a first end bent to form a receiving opening and a second end having a receiving indentation, and a center portion connecting the first and second ends,
the first end receiving opening receiving an edge portion of the first flange of the railroad rail,
the second end receiving indentation receiving an edge portion of a second flange of the railroad rail,
the one piece rail anchor being positioned adjacent one of the longitudinal edges of the elastomeric plate,
the center portion of the rail anchor arched away from a bottom surface of the rail, and a lowest bottom surface of the center portion extending downwardly an amount more than a vertical extent of the rigid steel plate but an amount less than a vertical extent of the fiat bottom surface of the elastomeric plate so as to avoid contact between the rail anchor and the concrete railroad tie.
9. The rail anchor assembly of claim 8
wherein the elastomeric plate is formed of a high density polymer.
10. The rail anchor assembly of claim 8
wherein the rail anchor has a generally rectangular cross section and wherein a bottom surface of the center portion extends downwardly from the top surface of the rigid plate supporting the railroad rail no more than 1.0 inches (2.5 cm).
