|BIDDLE interlocking with new M3 point machines.|
On the Shore Line a new interlocking, LIBERTY, has been commissioned west of the Kingston, RI station to support the new third track and island platform.
Around Boston, the ACSES PTC system is being installed on North Side MBTA lines, although it is not clear if this is in conjunction with cab signals or not. Normally ACSES is designed to work in conjunction with cab signals and ATC, but modifications to allow operation without cab signals is within the real of possibility. Also notable is thatACSES transponders have not appeared in the Guilford Rail System territory, which is generally exempt from the PTC requirement and has demonstrated hostility towards installing it for the Amtrak service if not required to.
For some updates regarding recently reported stories, the Rule 562 'C' boards are up in both directions at OAK interlocking, although not in service and all of the PRR pedestal signals on the SEPTA trunk line between Suburban Station and 30th St station have been replaced by the new ersatz variety.
