  • Crashwalls – AREMA specifications, Chapter 8, Article 2.1.5 covers requirements. Crashwalls are required when face of the pier is closer than 25 feet from the center line of the track.


Railroad s requirements drainage

Railroad’s RequirementsDrainage

  • Drainage from the bridge shall be preferable collected with drain pipes and drained away from the railroad right of way. When open scuppers are provided on the bridge, none shall be closer than 25 feet of the centerline of track. Flow from scuppers shall be directed away from the railroad drainage ditches.


Railroad s requirements structure excavation and shoring

Railroad’s RequirementsStructure Excavation and Shoring

  • Shoring protection shall be provided when excavating adjacent to an active railroad track, except as noted below:

    1) Excavation does not encroach upon a 1 ½ horizontal: 1 vertical theoretical slope line starting 1foot 6 inches below top of rail and at 12 feet minimum from centerline of track.

    2)Track is on level ground or in a cut section and on stable soil. (see railroad design manual)


Railroad s requirements general

Railroad’s RequirementsGeneral

  • Railroad Valuation Station and the distance from the nearest mile post at the intersection of the centerline of the track and the centerline of the bridge shall be shown on the plans.

  • Horizontal and vertical clearances shall be clearly marked.

  • At least one subsurface exploration boring for each substructure unit adjacent to the track shall be furnished. (see railroad design manual)


Railroad s requirements demolition of existing structure

Railroad’s RequirementsDemolition of Existing Structure

  • Railroad tracks shall be protected from damage during demolition of existing structure or replacement of deck slab. Either method may be used:

    1) a protection shield shall be erected over the track to catch falling debris

    2)track may be protected by timber matsplaced over the track structure (see railroad design manual)


Railroad s requirements erection procedure

Railroad’s RequirementsErection Procedure

  • The contractor shall submit a detailed procedure for erecting the spans over the railroad tracks. The procedure shall indicate the capacity of the cranes, location of the cranes with respect to the tracks and estimated lifting loads. The procedure must be approved by the railroad


General railroad information

General Railroad Information

  • Review time – the railroads usually require at least 2 months per each review

  • Railroad’s require as built plans

  • When performing work on railroad right of way before the project is awarded the consultant will need to obtain a right of entry (contact CO rail coordinator)

  • Flaggers maybe required when work is being performed in railroad right of way and within 25 feet of the railroad tracks

NARRATIVE OF BRIDGE ALTERNATIVESThe Structure Type Study shall include a brief narrative identifying the structure alternatives and their costs. The narrative should provide in­sight into why the particular proposed structure was chosen. Factors that need to be considered in selecting a structure for a particular site include geometry, economics, maintain­ability, constructability, right-of-way constraints, disruption to the traveling public, waterway crossing requirements or grade separations requirements, clearances for railway and highway crossings, foundation considerations, historical and environmental concerns, debris and ice flow problems and ap­pearance.


Railroad involvement relating to bridge design

202.2.4 SUPPLEMENTAL SITE PLAN FOR RAILWAY CROSSINGS

  • For Railway-Highway grade separation structures, a Supplemental Site Plan is required. The Supplemental Site Plan should be completed and submitted with the Final Site Plan (STEP 8). The reproduced tracing of this plan should have the title block deleted so that the railroad can use the plan to show force account work necessary to complete the highway project.

608 RAILROAD GRADE SEPARATION PROJECTS608.1 CONSTRUCTION CLEARANCEObtain the actual dimensions used in the text of this note from the "Agreement" (a legal document signed by the Director and Railroad). To help limit project construction problems, validate those dimensions with the district railroad coordinator before the note is considered complete. Revise the note to define the agreed upon restraints, including items such as short term clearances, if different than the construction clearances; maximum period of time for restricted clearances; or other project specific controls.
