The system, according to claim 1, wherein said predetermined power supplied to said at least one heating element is a predetermined voltage. 10. The system, according to claim 9, wherein said voltage is one of about four hundred and eighty (480) volts of alternative current and between about six hundred (600) and about seven hundred and fifty (750) volts of direct current. 11. The system, according to claim 1, wherein said system includes a fuse operatively connected between said power switch and said at least one heating element so as to protect said system from excessive current. 12. The system, according to claim 1, wherein said at least one heating element is mounted under and in close proximity to a top surface of said at least one floor panel. 13. The system, according to claim 12, wherein said at least one floor panel includes a floor covering disposed on a top surface thereof and wherein said at least one heating element is operable to limit a surface temperature of said floor covering to about one hundred and twenty five (125) degrees Fahrenheit. 14. In combination with a transit vehicle, said transit vehicle selected from the group consisting of rail car, passenger rail vehicle, passenger transit bus, passenger utility bus, and school bus, a system for generating radiant heat within interior portion of said transit vehicle, said system comprising: (a) at least one floor panel mounted above a sub-floor structure of said transit vehicle and being sufficiently rigid so as to meet rigors of passenger traffic in a mass transit environment and having each of a predetermined shape and a predetermined size, said at least one floor panel further having at least one heating element disposed therein;(b) a power switch operably disposed intermediate a power supply source of said transit vehicle and said at least one heating element for selectively providing and discontinuing a supply of a predetermined power generated by said power supply source to said at least one heating element; and(c) said at least one heating element at least includes an electrical conductor, an insulation layer surrounding said electrical conductor, a jacket surrounding said insulation layer and a metallic braid surrounding said jacket. 15. In combination with a transit vehicle, said transit vehicle selected from the group consisting of rail car, passenger rail vehicle, passenger transit bus, passenger utility bus, and school bus, a system for generating radiant heat within interior portion of said transit vehicle, said system comprising: (a) at least one floor panel mounted above a sub-floor structure of said transit vehicle and being sufficiently rigid so as to meet rigors of passenger traffic in a mass transit environment and having each of a predetermined shape and a predetermined size, said at least one floor panel further having at least one heating element disposed therein;(b) a power switch operably disposed intermediate a power supply source of said transit vehicle and said at least one heating element for selectively providing and discontinuing a supply of a predetermined power generated by said power supply source to said at least one heating element; and(c) said power switch is a contactor having a coil and at least one set of open contacts disposed therein, wherein a supply of a control signal to said coil causes said open contacts to close allowing flow of said supply power therethrough. 16.
