A railroad rail support includes a first and second horizontally oriented rubber tire having a circumferential tread, a top sidewall including a top rim bead and a bottom sidewall having a bottom rim bead, said bottom sidewall and bottom rim bead being adjacent to a railroad roadbed. First and second rail support members within each tire have a top surface in the plane of the top rim bead and a bottom surface in the plane of the bottom rim bead, and include a top plate and a plurality of tubular channels extending downwards from said top plate to the bottom surface. A concrete matrix fills each rubber tire and retains the rail support within the rubber tire. Railroad spikes are installed into the tubular channels have heads overlapping the opposed edges of the bottom flange of a first and a second railroad rail. Each spike is locked into its respective tubular channel by extending downwards in a generally vertical direction, with a second contiguous portion at an angle of at least 30 DEG from the vertical direction to said first portion. A female threaded member retained within each rail support member is on a common horizontal axis at a right angle to the rails, the female threaded members extending through each respective tire tread. A rail spacing adjustment has a first end extending into the first rail support female threaded member and has a right-hand thread and having a second end extending into the second rail support female threaded member and having a left-hand thread.
