Posted by Sand Box John on Fri Apr 8 22:57:32 2011, in response to Re: Metro Station at Dulles Airport to be Built Underground, posted by Hank Eisenstein on Fri Apr 8 12:06:31 2011. The station should be designed with wider than normal escalators, and an additional set of elevators. The platform should be wide enough for four-abreast walking at a minimum when passing stairs and other station appliances.The plan for the station in the FEIS shows 2 escalators of the width that is the standard to all WMATA stations, 48" wide stair treads. Between those escalators is a flight of stairs that have a foot print that is equal to the combined foot print of both escalators 5' 8 1/4" X 2. All of the station on the new line will have a minimum of 2 elevators between the various levels. The 2 elevator minimum became the new standard on WMATA when the G Route Blue line was extended to Largo. The minimum width of a platform in a twin platform station is 13'. The width of the platforms in the Forest Glen and Wheaton stations is 13' 7". The width of the island platforms in 10 of the 11 station on the new line is 30' 1/2". The Dulles Airport station, the 11th, is shown as being 40' wide in the FEIS. John in the sand box of Maryland's eastern shore. |
