 Metro is looking for vendors to design a new way for riders to get from the platform onto the train as part of a new pilot program. The doors in the pilot program will be tested at one underground and one above ground station on the Red Line. Some of the questions that vendors have to answer in the request for information include how the screen doors mitigate the risk of pinching passengers and what are the safety features for evacuation. The deadline for proposals is August 16th. Valerie Bonk, WTOP News.
