Section 2: Plan Layout (Exhibit A)
Anchor: #i1000209Introduction
The district prepares the plan layout (known as Exhibit A) for the project in sufficient detail to show all work to be performed by TxDOT, TxDOT’s contractor, and the railroad. Exhibit A includes:
- project data
- a title block
- right-of-way requirements
- a work list
- general notes
- warning signal device location.
Discussions of each of these items follow.
NOTE: All plan layouts prepared by the district must be signed, sealed, and dated by a registered professional engineer.
Anchor: #i1000259Project Data
Project data include:
- the county
- county number
- project description
- project number
- control-section-job (CSJ)
- railroad mile post (RRMP)
- highway station
- highway number or road name.
Title Block
The title block includes:
- the railroad company name and DOT No. (if available)
- crossing location
- railroad milepost and highway station at each location
- the words “Exhibit A.”
Right-of-Way Requirements
If the roadway is being widened, the plan layout should indicate if additional railroad right-of-way will be required. This is necessary for preparation of a new “license to cross” article in the agreement.
Anchor: #i1000349Work List
The work list provides a breakdown of all work to be performed by TxDOT, TxDOT’s contractor, and the railroad. The type of work to be performed on the railroad’s ROW should also be listed. When coring is involved, it is important to show where the coring will be performed in relation to the railroad tracks.
Anchor: #i1000359General Notes
General notes should include:
- number and speed of “through” trains per day
- number and speed of switching moves per day
- average daily traffic (ADT)
- posted speed limit of vehicle traffic.
Warning Signal Device Location
On roadway modification projects, if railroad warning signal devices exist, their existing location and the proposed new location of the warning signals and appurtenances must be shown.
NOTE: If widening of the roadway involves relocating or upgrading the existing railroad warning signal devices, it is important to include pictures of the location.
On new road construction projects, the railroad warning signal devices are installed under terms of a separate agreement with the railroad company prepared by the Traffic Operations Division (TRF). The district should submit one additional copy of the Exhibit A to TRF for preparing the signal agreement and developing the railroad warning signal device portion of the project. A diagnostic inspection is normally conducted prior to determining the type and location of the railroad warning signal devices to be installed (see Chapter 6, Section 6, of this volume for details). TRF schedules the diagnostic inspection, which involves representatives from the district, the railroad company, and local government (as necessary).
