Construct apecial trackwork on ballasted track and embedded track with no reil cant. <br /> 2. Construcl ballasted treck and embedded lracks with reil cant el 40 to 1 inward inclination o1 <br /> �h@ rai18. <br /> 3. TransKioning of the r&il cant shall be as shown on the Contraci Drewings. <br /> F. Superelevation: <br /> 1. Superelevate lrack curves as indicated on the Conlract Drawmgs, <br /> 2. Turnouta and Crosaovers shall nol be supereleveted. <br /> 3. Metal teps shall be installed to merk the beginning end ending points of supe�elevation and <br /> every tl4-inch increment belween lhe beginning and ending pointa of the superelevation <br /> trensition.Atlached or bond lags lo timber tiea approximetely 1 toot inside the oulside rail to <br /> read in the direction of increasing stalioning. <br /> 4. Track curve information shall be as indiceted on the Contract Drewings. <br /> G. Track Suriace: <br /> 1. Treck suriace is the relalionship of both rails opposite each other in profile and croas level. <br /> Treck profile is the running surface along the top ot lhe rails. Croas level is the diHerence in <br /> elevation belween the top oi heads of apposita rails measured et right angles to the treck <br /> atignment. The ideal suAace is a unifortn profile consisting ot straight gradienls connected by <br /> vertical curves,with zero cross level on tanpents and predetermined cross level on curvea. <br /> 3 4 TRACK CONSTRUCTION TOLERANCES <br /> A.
