the tracks in question, normal and over-dimension (including U.S. Department of Defense Strategic<br />
Rail Corridor Network), and the history and nature of over-dimension movements. Where an actual<br />
conflict exists with a specific station platform height, care should be taken to determine whether a<br />
lower platform height corresponding with lower-floor and –entry rolling stock is possible.<br />
Project Sponsors should take into account construction of station platforms on curves due to issues that<br />
make it impossible to achieve level boarding since this situation results in significant gaps that exceed<br />
the dimensions usually allowed for level boarding at station platforms. Ideally, station platforms<br />
should be constructed on tangent track. Though, if necessary, platforms could be on a mild curve of no<br />
more than 1 degree 40 minutes with little or no super-elevation.<br />
As outlined in the DOT’s Level Boarding Guidance dated September 1, 2005, if full level boarding<br />
meeting the gap requirements (3-inch horizontal gap and 5/8-inch vertical gap, or 1.5-inches for<br />
existing vehicles operating in new stations) is not possible, other choices are offered in a hierarchal<br />
order of preference:<br />
1) High-level platforms in conjunction with short bridge plates providing access to each car.<br />
2) Car-borne or station-based lifts serving each accessible car.<br />
3) Gauntlet or bypass tracks where necessary to accommodate over-dimensioned freight loads<br />
along high-level platforms.<br />
4) Mini-high platforms.<br />
3.0 OBJECTIVES<br />
The objective of this review is to ensure compliance with ADA level boarding starting with project<br />
planning (site planning of stations and platforms), and continuing through design and construction.<br />
This review is meant to bring to light as early as possible perceived impediments to compliance, serve<br />
as a platform for the generation of ideas and recommendations for removal of impediments so that<br />
compliance can be achieved.<br />
4.0 REFERENCES<br />
The following are the principal, but by no means the only, references to <strong>Federal</strong> legislation, regulation<br />
and guidance with which the PMOC should have a good understanding as related to the Grantee’s<br />
project work being reviewed under this OP:<br />

• 49 CFR Parts 27, 37 & 38: U.S. Department of Transportation regulations implementing the<br />
transportation provisions of the ADA.<br />
o The Department issued a Final Rule adopting new accessibility standards effective<br />
November 29, 2006. Through this final rule, the Department amended its ADA<br />
regulations to adopt, as its regulatory standards for accessible transportation facilities,<br />

2004 by the Access Board as well as the Board's subsequent technical amendments.<br />

accessible routes relative to general circulation paths, and 810.5.3 regarding the<br />
