===643.4.1.5 Grade Separation Structures / Closing of Existing Crossings===
The design of railroad-highway grade separations is coordinated with Bridge and district Design. [[:Category:747_Bridge_Reports_and_Layouts|EPG 747 Bridge Reports and Layouts]] provides information for creating a grade separation report.

A minimum lateral clearance and vertical clearance from the railroad track to the structure is required. (For additional information see [https://epg.modot.org/index.php?title=Category:760_General_Construction_Inspection_for_Structures#760.4.4_Railroad_Vertical_and_Horizontal_Clearances EPG 760.4.4 Railroads Vertical and Horizontal Clearances].) The right angle section must extend entirely across the railroad's right of way.

At an early stage in the design process, the district will coordinate efforts with MO-RR to explore the feasibility of closing adjacent at-grade crossings that may or may not be located on the state highway system. Should this be the case, the closing of the other crossings will be a part of the grade separation project.

[http://www.up.com/real_estate/roadxing/industry/index.htm BNSF Railway-Union Pacific Railroad Guidelines for Railroad Grade Separation Projects] provides specific guidelines as required by these railroads when constructing over or under railroad property.

Railroads often request information to be included within the initial submittal. When preparing concept or preliminary plans for railroad review, include the following when possible:

Item No. Sheet Comment
1. TITLE Identify RR location: Add Railroad milepost number and subdivision. Add latitude and longitude. Add DOT number.
2. PLAN Add north arrow. Add timetable directions and direction to next station. Show increasing or decreasing MP to next station.
3. PLAN Show limits of RR ROW (on elevation & profile)
4. PLAN Show individual span length and total bridge length
5. PLAN On new structures, show future track with access road.
6. PLAN Provide all existing and any proposed horizontal and vertical clearances (even when they will not change)
7. PLAN Add note: “Access to RR ROW to be maintained at all times and public use of railroad access road is not allowed.”
8. PLAN Drainage directional arrows at slopes

==643.4.2 Construction Inspection Guidelines for Railroads==
[[image:643.4.2.jpg|right|275px]]
There are two basic types of railroad projects that require oversight and inspection by MoDOT construction inspectors:

:* Highway construction projects built by MoDOT contractors over, on, or under railroads. The work on these projects use traditional job numbers (JXXXXX). MoDOT’s Railroad Projects Manager (RPM)is the Central Office contact for any questions concerning this type of railroad work. Refer to [[#643.4.1.1 Highway Construction Projects With Railroad Involvement|EPG 643.4.1.1 Highway Construction Projects With Railroad Involvement]] and [[#643.4.1.2 Contract Job Special Provisions Detailing Railroad Requirements|EPG 643.4.1.2 Contract Job Special Provisions Detailing Railroad Requirements]].
:* Railroad crossing safety improvement projects built by the railroad or their contractor. Railroad crossing safety improvement projects typically use the following style of job number: RRP-000S(XXX). MoDOT’s Railroad Safety Specialists (RSS) are the Central Office contact for any questions concerning this type of railroad work.

Highway construction projects usually involve state routes only, whereas the railroad crossing safety improvement projects can be located on any public crossing, including but not limited to crossings located on city streets, county roadways or highways.

===643.4.2.1 Railroad Flagging===

A railroad flagger is a railroad employee designated to communicate with our contractor. A flagger is required whenever the contractor’s work could endanger or interfere with the railroad’s operations such as the movement of trains through the project site. A general rule is a flagger is required whenever the contractor will have workers or equipment within 25 feet of the centerline of an active track. One of the primary duties of the flagger is to advise the contractor when trains are expected so that the contractor can pull back personnel and equipment to secure the construction area for the safe movement of trains. The department’s contractor shall contact the railroad to hire a flagger under the conditions specified in the JSP; however, if the contractor proceeds without a flagger when one is needed, the railroad may choose to station a flagger at the site full time throughout the project duration. Under most circumstances a flagger cannot be hired on an hourly basis. Typically the flagger is hired for a minimum of one eight-hour day. Some railroads require as much as 30 days advance notice to hire a flagger and as much as one week’s notice to discharge a flagger, so the contractor is economically inclined to consolidate all work that requires flagging service. Flagging costs are deducted from the contractor’s progress payments. There is no bid item for flagging service. The contractor’s costs for flagging must be in other bid items. The project office shall review all flagging invoices for accuracy, thus inspectors should keep an independent record of the flagging service provided.

Since flagging costs can quickly become extremely expensive, MoDOT districts are urged to strictly monitor the charges and ask MO-RR for assistance should they appear unreasonable.

===643.4.2.2 Adjustment of Railroad Facilities===

Railroad facilities may need to be modified or adjusted to clear the construction area. For example overhead communication lines frequently need to be relocated prior to the construction or demolition of a highway bridge over a railroad. Sometimes the railroad tracks need to be moved to make space for a new bridge pier. Railroad employees perform these adjustments at MoDOT expense. Ideally this type of work is performed prior to the start of the project construction. The project office inspects these adjustments and makes recommendation for payment when the railroad invoices are received.

===643.4.2.3 Field Inspection of Railroad Work===

Inspection of work performed by railroads during highway construction projects is similar to the inspection of work performed by [[643.2 Local Utility Adjustments - Public and Private#643.2.2.6 Field Inspection|utility companies]]. The railroad is responsible for the work that will be reimbursed by MoDOT, but the work is performed on their facilities in accordance with their own standards. The RE’s office or MO-RR staff will keep detailed records of the work performed so the [[643.2 Local Utility Adjustments - Public and Private#643.2.2.8 Maintaining Construction Records|railroad invoices]] can be verified in the following situations.

===643.4.2.4 Railroad Invoices - Highway Construction Projects===

On MoDOT construction projects in which, for example, a bridge is built over a railroad, MoDOT’s Railroad Projects Manager (RPM) receives the progressive and final invoices from the railroads. The RPM will forward all invoices to the RE. The RE’s office is responsible for reviewing and making recommendation for the payment for all railroad work performed for highway construction projects. Railroads may send progressive invoices for facility adjustments and for flagging services on a monthly basis. The project office shall determine the amount of flagging costs that need to be deducted from the contactor’s payments. The project office should process the invoices within one month of receipt when possible. Progress invoices are handled in the same manner as the [[643.2 Local Utility Adjustments - Public and Private#643.2.2.9.2 Partial Payment Invoices|utility partial payment invoices]]. Therefore, the RE sends progress payment memos directly to the Controller’s Office (copy memo to Division Construction and the RPM (not the DUE)). Final invoices are processed in the same manner as [[643.2 Local Utility Adjustments - Public and Private#643.2.2.9.3 Final Invoice|Utility Final Invoices]]. However, the RE will forward the following items to the Construction Division with a memo:

:* [https://epg.modot.org/forms/CM/C9_Daily_Utility_Report.pdf Daily Utility Reports (C-9)] and the
:* [https://epg.modot.org/forms/CM/C13_Final_Utility_Report.pdf Final Utility Report (C-13)]

The district construction office and the RPM also receive copy of the memo and attachments. If disputes are encountered between the contractor and the railroad representatives that cannot be resolved by the RE, or if questions arise regarding the intention of construction and maintenance agreements or railroad special provisions, the project office can contact the RPM.
