Gravel Place, Pennsylvania : ウィキペディア英語版 | Gravel Place, Pennsylvania Gravel Place is a location within Arlington Heights, Monroe County, Pennsylvania. It is neither incorporated nor a census-designated place but has a federally recognized name by the USGS.〔(【引用サイトリンク】title=Gravel Place Populated Place Profile / Monroe County, Pennsylvania Data )〕 It was the former interchange between the DL&W and the WB&E railroads near present Mill Creek Road and featured a mechanical switch tower to control the switching of tracks. There were connections to a roundhouse used for helper locomotives. In 1942, the switching towers at West Henryville and Analomink were replaced by electric interlockings, remotely controlled from the Gravel Place tower. The equipment at Gravel Place was moved to another tower (in East Stroudsburg) in 1950; thereafter Gravel Place was unmanned.〔http://www.monroehistorical.org/articles/files/2014_11_rail-tower.html〕 ==References==
