I claim: 1. A concrete railroad tie comprising: an elastic rail support; lateral, raised shoulders and a support region disposed between a base of a rail and said raised shoulders, the rail being longitudinally received in a crosswise direction of said elastic rail support; guide plates including twisting-prevention devices disposed in said supporting region; a support area for supporting said guide plates, said support area being essentially flat without continuous, deep depressions beneath said guide plates; said support area includes outer edges, each of said outer edges comprising depressions spaced apart in said crosswise direction for preventing twisting; and said twisting-preventing devices of said guide plates comprising spaced lugs, said spaced lugs engaging respective ones of said depressions. 2. The concrete railroad tie of claim 1, characterized in that the support area (3") is provided with centrally disposed elevations (20), which, on the inside, form the boundary of the guide plates (6"). 3. The concrete railroad tie of claim 1, characterized in that the support area (3"), in the region of each guide plate ( 6"), preferably has two lateral lugs (16, 16", 18 ), which engage appropriate recesses in the guide plates (19, 19", 19""). 4. The concrete railroad tie of one of the claims 1 and 2- 3, characterized in that the lugs (16, 16"), which prevent twisting, are cemented on. 5. The concrete railroad tie of claim 3, characterized in that the lugs (18), which prevent twisting, are formed by dowels, especially by plastic dowels (18), which are pressed into pre-fabricated recesses (17) of the concrete (2) or cemented in during the fabrication. 6. The concrete railroad tie of claim 1 wherein said tie is a two block railroad tie. 7. A concrete railroad tie comprising: an elastic rail support, said rail support including a supporting region for supporting a rail foot in a crosswise direction of said elastic rail support, said supporting region being essentially flat, said rail support further including lateral, raised shoulders; guiding plates disposed on said rail support in said crosswise direction of said elastic rail support and located adjacent to said shoulders; twisting-preventing devices disposed on both of said rail support and said guiding plates between said supporting region and said shoulders; said twisting-preventing devices on one of said supporting region and said guiding plates including depressions spaced apart in said crosswise direction and an other one of said twisting-preventing devices on a remaining one of said supporting region and said guiding plates including lugs, said depressions correspondingly positioned for engaging respective ones of said lugs for preventing twisting. 8. A concrete railroad tie comprising: a rail support including a pair of raised shoulders and a support region disposed between said pair of raised shoulders on which a rail foot is supportably receivable positioned in a crosswise direction of said rail support; guiding plates receivable to the rail support in said crosswise direction and positionable within said support region for lateral support against said pair of shoulders; a one of said supporting region and said guiding plates including depressions spaced apart in said crosswise direction, and a remaining one of said supporting region and said guiding plates including lugs, said lugs being correspondingly positioned with respect to said depressions such that said depressions and said lugs respectively engage one another, thereby acting to inhibit twisting of the guiding plates when received to said supporting region. 9. The concrete railroad tie of claim 8 wherein said tie is a two block railroad tie. 10. The concrete railroad tie of claim 8 wherein said depressions are provided in said supporting region in a region adjacent to said raised shoulders and proximate to opposed side boundaries of the rail support in the crosswise direction, said lugs being carried on a lower support surface of said guiding plates.
