A method and an apparatus for the protection of a railroad rail, a direct fixation plate or another support unit, a rail to rail connection and a rail to plate connection contacting with concrete upon placing of concrete during construction. The method comprises a step of disposing a mask over a railroad track having a railroad rail, a rail connector and a rail tie to protect the railroad track while placing concrete, the mask configured to cover the rail connector and tie. The mask has a connecting portion, a central portion, an extending portion configured to mask an upper longitudinally extending portion of a railroad rail, and at least one perpendicular section disposed to cover a railroad tie, direct fixation plate or other support unit.

1. A method of placing concrete around and under a railroad rail, the railroad rail having a concrete framework around and under said railroad rail, the railroad rail being connected to a plurality of ties with a plurality of connectors, said method utilizing a mask configured to be disposed to mask
1. A method of placing concrete around and under a railroad rail, the railroad rail having a concrete framework around and under said railroad rail, the railroad rail being connected to a plurality of ties with a plurality of connectors, said method utilizing a mask configured to be disposed to mask the railroad rail, rail connectors and ties when placing a concrete slab, said method comprising the steps of: disposing said mask over an upper portion of the railroad rail, rail connectors and tie plates and ties;placing concrete over and around said mask into the concrete framework, frameworking a concrete slab; andremoving said mask from the railroad track, having filled the concrete framework to construct a concrete encasement under and around the railroad track. 2. The method of placing concrete around and under a railroad rail of claim 1, wherein said mask comprises a plurality of masks, each said mask being configured to be disposed to mask the portion of railroad rail extending between adjacent masks, said step of disposing said mask over an upper portion of a railroad rail and rail connector further comprises disposing said plurality of said masks about a length of the railroad rail wherein each said mask is disposed to mask the portion of railroad rail extending between adjacent masks. 3. The method of placing concrete around and under a railroad rail of claim 2, wherein said step of disposing a plurality of masks about a length of railroad rail further comprises disposing a plurality of masks about two parallel lengths of railroad rail. 4. The method of placing concrete around and under a railroad rail of claim 1, wherein said mask comprises at least one handle configured for disposing the mask over the upper portion of the railroad rail and rail connector and removing it therefrom. 5. The method of placing concrete around and under a railroad rail of claim 1, wherein said mask comprises a connecting portion, a central portion, and an extending portion configured to mask an upper longitudinally extending portion of the railroad rail, said connecting portion being configured to be disposed about said extending portion of an adjacent mask disposed over the railroad rail. 6. The method of placing concrete around and under a railroad rail of claim 1, wherein said mask comprises a planar bottom edge. 7. The method of placing concrete around and under a railroad rail of claim 6 wherein said step of placing concrete over and around said mask into the concrete framework further comprises placing concrete in an amount sufficient to contact said planar bottom edge of said mask. 8. A method of installing concrete for supporting a railroad tie, said tie being configured to support a railroad rail and cooperate with rail connectors, said method utilizing a mask configured to be disposed to substantially mask the railroad rail, rail connector, and tie from the placing of concrete, said method comprising the steps of: disposing said mask over an upper portion of the railroad rail, rail connector, and tie disposed therewith;placing concrete over and around said mask;removing the mask from the upper portion of the railroad rail, rail connector, and or tie disposed therewith; andcuring the concrete frameworking a concrete slab supporting the railroad tie. 9. The method of installing concrete for supporting a railroad tie of claim 8, wherein said tie is a concrete tie, said method further comprising an initial step of placing a concrete framework under said tie frameworking a cavity therein parallel with the railroad rail supported therewith, and said step of placing concrete over and around said mask and into the concrete framework further comprising placing concrete into each concrete framework. 10. The method of installing concrete for supporting a railroad tie of claim 8, wherein said mask comprises a plurality of masks, each said mask being configured to be disposed to mask each tie and the portion of railroad rail extending between adjacent ties, said step of disposing a mask over an upper portion of the railroad rail, rail connector, and tie disposed therewith further comprises disposing a plurality of masks about a length of railroad rail wherein each said mask is disposed to mask each tie and cooperate with adjacent masks to mask the portion of railroad rail extending between adjacent ties. 11. The method of installing concrete for supporting a railroad tie of claim 8, wherein each said mask comprises at least one handle configured for disposing the mask over the upper portion of the railroad rail, rail connector, and tie disposed therewith and removing it therefrom, after said step of placing concrete about said mask and into the cavities in the concrete framework. 12. The method of installing concrete for supporting a railroad tie of claim 8, wherein said mask comprises a connecting portion, a central portion, and an extending portion configured to mask an upper longitudinally extending portion of the railroad rail, said connecting portion being configured to be disposed about an extending portion of an adjacent mask disposed over the railroad rail. 13. The method of installing concrete for supporting a railroad tie of claim 8, wherein each said mask comprises a planar bottom edge configured to be disposed with a lower planar surface of the base plate or tie upon which it is disposed. 14. The method of installing concrete for supporting a railroad tie of claim 13, wherein said step of placing concrete over and around said mask and into the concrete framework further comprises placing concrete in an amount sufficient to contact said planar bottom edge of each said mask.
