With service beginning in 1907, the Philadelphia & Western Railway was one of many interurban railroads built in the United States in the early 20th century. Most of the P&W still operates today as SEPTA's Norristown High Speed Line, but a portion of the right-of-way through Radnor Township sat abandoned from 1956 until 2004, when it was re-purposed as the Radnor Trail. Interpretive signage was created for the trail to salute the history of the P&W and mark the spots where stations once stood. (Designed with Cloud Gehshan Associates)
