By MyFM's Rick Michaels - Commuters attending a public meeting last month in Franklin, hosted by State Representative Jeffrey Roy expressed their frustrations over delays on the Franklin Commuter Line and were told changes are on the way and some of that change could begin this week. The MBTA and the Massachusetts Department of Transportation is undertaking federally mandated Positive Train Control (PTC), infrastructure installation this is aimed at increasing the safety of commuter rail customers. Test trains of the (PTC) System, engineered to prevent accidents will be operating on the tracks of the Franklin Line throughout the week during the overnight hours when passenger train service is not running. Older signaling systems have been upgraded to make them compatible with (PTC) with the hope of making trains more reliable and much less likely to cause service delays. Work is also continuing on the tracks along the Franklin Line which will result in double racking along a greater stretch of the commuter line this work is primarily being done on weekends, resulting in shuttle service from Forge Park to the Readville Station this is expected to continue until sometime in March.
