I have 4 Atlas O double track pratt truss bridges that I have taken the tracks off and put GarGraves in its place. I want to lay the 2 extra rails like what is on real trestles and I am trying to find out if the rail that Atlas uses is 148? I know GarGraves makes A 5 rail track but I have the ties spaced closer together and screwed down to the bridges already. Thank you for any help Choo Choo Kenny
