WMATA was smart to remove carpet from the 7K series, but there are still padded seats. WMATA should follow the design ideas of other mass transit agencies like MTA/NYC and Chicago's L-train and not require padded seats in future railcar designs. (If there is a design in progress at this time, recommend WMATA issue a change order modification to eliminate the requirement for padded seats immediately!) It's wasteful and is an added cost for upkeep to replace them. (I worked at WMATA, so I know a thing or two about having to buy new pads for the railcar seats. LOL) And WMATA cannot afford any frivolent costs for maintenance.
