A clamp for non-invasively attaching components to railroad track rails. The clamp provides a receiving slot for receiving a first flange of a track rail between upper and lower legs. Disposed within the slot is a resilient member or spring that is compressed when engaged by the first flange of the track rail. Compression of the resilient member allows for positioning a tab attached to a free end of the lower leg over an outside edge of a second flange of the track rail.

1. An anchor for securing a component relative to a surface of a track rail, comprising: a U-shaped body having: an upper leg adapted for disposition above a first flange of a foot of a track rail;a lower leg for disposition beneath the first flange of the foot of the track rail, the lower leg having a free end with a tab attached thereto extending in a direction transverse to said top surface of said lower leg; anda closed end between said upper leg and said lower leg, wherein a bottom surface of said upper leg and a top surface of said bottom leg are disposed in a spaced and opposing relationship sized to receive the first flange of a track rail there between;a resilient member positioned between said upper leg and said lower leg, wherein: a first portion of said resilient member is compressed between the upper leg of said U-shaped body and the first flange of the foot of the track rail when the first flange of the foot of the track rail is disposed in said U-shaped body between said upper leg and said lower leg: anda second portion of said resilient member is positioned relative to said U-shaped body such that it is compressed between said closed end of said U-shaped body and an outside edge of the first flange of the foot of the track rail when the first flange of the foot of the track rail is disposed in said U-shaped body between said upper leg and said lower leg;wherein said tab is adapted to engage the outside edge of the second flange of the track trail when the track rail is disposed in said U-shaped body between said upper leg and said lower leg and the second portion of the resilient member is compressed. 2. The anchor of claim 1, wherein said lower leg has a length greater than the width of the track rail measured from opposing outside edges of the first flange and a second flange of the track rail. 3. The anchor of claim 2, wherein said resilient member is fixedly attached to said upper leg. 4. The anchor of claim 1, wherein said second portion of said resilient means, when compressed, provides an expansive force between said closed end of said U-shaped member and said tab attached to said free end of said lower leg. 5. The anchor of claim 1, wherein said tab has a length that is less than or equal to a thickness of the outside edge of the second flange of the foot of the track rail. 6. The anchor of claim 1, wherein said resilient member comprises: a leaf spring. 7. The anchor of claim 1, wherein an expansive force of said first portion of the resilient member, when compressed, maintains a portion of said top surface of said lower leg in contact with a bottom surface of the foot of the track rail. 8. The anchor of claim 1, wherein said upper leg has a length between a first end proximal to said closed end of said U-shaped member and a second end that is less than one-half the width of the track rail measured from opposing outside edges of the first flange and a second flange of the track rail. 9. The anchor of claim 1, further comprising: an engagement structure connected to said upper leg and extending in a direction transverse to a length of said upper leg. 10. The anchor of claim 9, wherein said engagement structure further comprises: a track engaging element attached to said engagement structure, wherein said track engagement element is configured for selective movement between a first position relative to said engagement structure and a second position relative to said engagement structure. 11. The anchor of claim 10, wherein said track engaging element comprises: a threaded element disposed though an aperture in said engagement structure. 12. The anchor of claim 10, further comprising: a bracket attached to said track engagement element, wherein said bracket is configured to compress a component to a surface of said track rail. 13. An anchor for securing a component relative to a surface of a track rail having a rail head and a foot with first and second flanges, comprising: a base portion sized to underlay a foot of a track rail, said base portion having a substantially planar top surface for positioning relative to a bottom surface of the foot of the track rail;a tab attached to a first end of said base portion and extending in a direction transverse to said top surface of said base portion, wherein said tab is adapted to engage an outside edge of a first flange of the track rail;an upstanding portion attached to a second end of said base portion and extending in a direction transverse to said top surface of said base portion, wherein said upstanding portion is adapted for positioning proximate to an outside edge of an opposing second flange of the track rail;a leg attached to said upstanding member at a location above said base portion and extending in a direction toward a centerline of the track rail anda resilient member associated with said upstanding portion, wherein: a first portion of said resilient member is compressed between said upstanding portion and the outside edge of the second flange of the track rail when said tab engages the outside edge of the first flange and said top surface of said base portion is juxtaposed relative to the bottom surface of the foot of the track rail;a second portion associated with said leg, wherein said second portion of said resilient member is compressed between said leg and a top surface of the second flange when said tab engages the outside edge of the first flange and the said top surface of said base portion is juxtaposed relative to the bottom surface of the foot of the track rail. 14. The anchor of claim 13, wherein said first portion of said resilient means, when compressed, provides an expansive force between said upstanding member and said tab. 15. The anchor of claim 13, further comprising: an engagement structure connected to said leg and extending in a direction transverse to said top surface of said base portion. 16. The anchor of claim 15, wherein said engagement structure further comprises: a track engaging element attached to said engagement structure, wherein said track engagement element is configured for selective movement between a first position relative to said engagement structure and a second position relative to said engagement structure. 17. The anchor of claim 16, wherein said track engaging element comprises: a threaded element disposed though an aperture in said track engaging element. 18. The anchor of claim 16, further comprising: a bracket attached to said track engagement element, wherein said bracket is configured to compress a component to a surface of said track rail.
