Section 5: Design Phase

Exhibit A Preparation

The District prepares the Exhibit A plan set following the diagnostic inspection to show all work to be done on the project by TxDOT, the local government, and railroad company.

For crossing closure projects, the local government may choose to prepare the Exhibit A plans showing details of the closure or may seek assistance from the District.

All Exhibit A’s must be signed, sealed, and dated by the engineer designing the plans.

On local roadways, the following items of work are typically constructed and paid for by the local government:

  • Median installation
  • Civil features such as curb & gutter, guardrail, retaining walls, and culverts
  • Traffic signal adjustments
  • Utility adjustments
  • Removing sight distance obstructions such as vegetation
  • Signing & striping (may be performed by TxDOT)
  • Roadway alignment improvements
  • Installing conduit for traffic signal preemption (typically reimbursed by TxDOT).

Districts may assume costs of these items for crossings on TxDOT roadways. The railroad company may be willing to perform these duties as part of negotiating the final agreement.

The railroad company provides materials and labor for:

  • active warning devices and railroad cabin
  • track circuitry
  • traffic control
  • providing a preemption connection between railroad cabin and traffic signal cabin
  • replanking (crossing surface).

These items are reimbursed by TxDOT under FSP funding.

For details on how to develop an Exhibit A plan set, see Chapter 7 of this manual.

TRF-RSS will review and approve Exhibit A’s, as well as any preemption forms, prior to preparing the individual project agreement.

Local Government Signature

If a local government manages the road at the at-grade crossing, the title sheet of the Exhibit A must be signed prior to submitting the Exhibit B to the railroad company. By signing the title sheet, the local government agrees to the work shown on the Exhibit A, responsibilities shown in the Master Agreement, and the cost participation shown in the estimate. The District Railroad Coordinator arranges to have the sheet signed.

Preemption Request Form

The railroad companies will review any preemption forms submitted for an FSP project. After approval, some railroad companies may request that a Preemption Request Form is completed and signed. The form clarifies which preemption circuits are requested on the project.

TRF-RSS will arrange to have the form signed by the District Traffic Signals Engineer. Preemption forms, reports, and request forms are uploaded into the TRIMS Project Management Module by the TRF-RSS Project Manager.

Cost Estimates

An estimate and wireline diagram is provided from the railroad company for labor and materials provided by the railroad company. The local government will produce an estimate for any labor and materials provided by the local government. Estimates will clarify any cost participation by the railroad company or local government. With the exception of funding TxDOT provides to local governments for closing crossings, materials and labor provided by the local government are usually not reimbursed via FSP funding.

For crossings on the state highway system, the District will pay for any TxDOT labor or materials out of District funds. This work is typically similar to work provided by a local government on an off-system crossing. Work by a TxDOT contractor is also paid out of District funds. An estimate for TxDOT services or TxDOT consultant services is not necessary since it is not attached to an individual project agreement.

The TRF-RSS Project Manager will review and approve all estimates prior to development of the Exhibit B, Force Account Agreement, or Crossing Closure Agreement.

For further information on reviewing railroad company cost estimates and wireline diagrams, see Chapter 2 of this manual.


TRF-RSS will request planning CSJs from the District Railroad Coordinator for all projects which will utilize federal funding to reimburse the railroad companies and local governments. After obtaining the planning CSJs, TRF-RSS will request each quarter that the Finance Division Letting Management Section provide construction CSJs for each of the planning CSJs. The Finance Division Letting Management Section will create a new FPAA to include the construction CSJs for an amount based on estimates to be paid out to railroad companies and local governments. FHWA will review and approve the FPAA.
