9.4.G. Right-of-Way and Utilities. (continued)An adjustment in the railroad line, such as raising or lowering tracks to accommodate highway construction,is occasionally necessary. In this case a special profile along the railroad alignment will show the full extentof the raising or lowering of tracks. Carry the profile a sufficient distance outside of the adjusted area to givea complete picture of the proposed adjustment.For a new crossing of the railroad tracks, prepare a special profile on either side of the crossing along the trackcenterline for several hundred meters.f. Cross Section Plots. Cross section plots prepared in elaborate detail are not necessary. However, forhighways encroaching on railroad property, it is advisable to show all the data obtained in the field.Computer generated plots are acceptable with the possible exception of partial sections for drainage andapproach design. For drainage sections, furnish elevations for inlets and outlets of pipe as well as channelelevations upstream and downstream. Show size and length of all drainage or other type structures in existenceand proposed on the new construction.Show railroad and highway information, including superelevation and widening where applicable.The cross sections are usually plotted on standard reproducible cross-section paper. Maintain ample spacebetween cross sections to ensure legibility.Show the railroad right-of-way lines on all cross sections. Make sure the distance shown on the cross sectionfrom the encroachment line to the railroad right-of-way will check the field ties shown on the plan sheet.Show the railroad and highway culverts on the cross sections and include the flow line elevations. This allowsthe consideration of extensions rather than relaying an existing pipe or installing a new one.Some projects require slope permits or ditch easements in addition to the regular encroachment. In these cases,the cross sections shall show the railroad right-of-way line, the easement line, and the sloping permit orchannel change line.When raising or lowering a railroad track is necessary for highway construction, plot cross sections along thecenterline of railroad tracks through the area affected.g. Final Assembly. Forward the completed plans, profiles, cross-section rolls, and structure clearance, ifapplicable, to the owner agency and request their review and comments. A request to begin preparation of theformal agreement can accompany this submittal.The final PS&E package review should ensure that the contract contains all conditions listed in the approvedrailroad agreement.4. Railroad Grade Crossings. Before designing improvements of existing crossings or new crossings,arrange for a field inspection of the crossing site. The review should involve appropriate <strong>Federal</strong>, State, local,and railroad representatives.The review should resolve financial responsibility, scheduling, and authorization to proceed with the work.The type, number and location of railroad signals to be installed should also be determined.9 - 120
