Second Train Coming Warning Sign Demonstration Projects
Report Number: RRD-51
Publication Date: 10/12/2002
A challenging problem that many light rail systems face is the "second train coming" phenomenon on double track crossings. A second train frequently activates the grade crossing equipment within seconds after the first train has activated the grade crossing circuits, thus creating a situation in which two trains pass through the grade crossing within seconds of each other which could be very confusing and potentially dangerous to motorists and pedestrains. This digest provides the results of two demonstrations of active sign warning systems that could increase awareness of and compliance with the conditions of the second train coming phenomenon.

Reducing the Visual Impact of Overhead Contact Systems
Report Number: R-7
Publication Date: 9/15/1995
This report defines Overhead Contact Systems (OCSs) and describes the function of OCSs for trolleybus and light rail systems. The report describes non-intrusive and intrusive designs, considering the overall visual impact of those designs on intersections or street segments and the complete effect that hardware has in any given location. It discusses the influence system design has on visual impact including the need for emergency wire and the use of one-way operation to minimize visual impact in trolleybus systems. Further, it investigates how the turning capability in trolleybus and light rail OCS design may have an effect on visual impact. The report considers the effect of curve design and the design of the electrical distribution systems on the appearance of light rail. An approach to evaluating the visual impact of trolleybus intersections is presented. This report concludes that the visual impact of OCSs can only be reduced if such reduction is made a specific goal throughout the design process.

Automatic Wheel Inspection Station
Report Number: IDEA-03
An automated railroad wheel profile inspection system designed to measure wheel profiles at operating speeds using a laser scanning technology was developed and trial tested in a bench-scale demonstration. A Transit IDEA product report was published in October 1995. In Stage 1, preliminary specifications and hardware design for the system, including layout and component specifications, were completed. Several laser sensors have been tested on actual railroad wheel segments to determine the overall feasibility of the proposed approach. A bench-scale inspection station system was designed, fabricated, and tested in the laboratory. In Stage 2, in-house trial tests of the system in simulated railroad conditions were performed and operational durability and reliability of the system examined. The cost-effectiveness was assessed and an operating design of the system for routine application by transit operators was developed.

The research uses the San Diego metropolitan area for a test bed, in collaboration with the major transit agency, the Metropolitan Transit Development Board(MTDB), and local and regional agencies, including the San Diego Association of Governments (SANDAG). Please note: This project is still in progress.
Optimizing Travel Path for People with Disabilities
Report Number: IDEA-23
