It seems that our friend at L&W signaling have expanded their product range from just the long out of production PRR Position Light pedestal signals, recently seen on SEPTA, to the more common position light dwarf signal, still available from Safetran and other suppliers.
Although LED drop in lamps are available for position light dwarfs (see the 6S signal above displaying Slow Approach), Amtrak chose L&W's boxy replacements for the 7S and 8S stick dwarfs at the northern end of TOWER 1 interlocking at Boston South Station.
This may or may not be related to the others doings a-happening at South Station in the form of a new Luxury hotel that will cover up the open air space at the north end of the platforms between the Bus station and the current train hall. About 2 car lengths have been cut from the platforms to make way for what I assume will be hotel space and with it the fixed PRR PL dwarf Stop indicator in front of the bumper blocks. Like the Tower 1 dwarfs, they have been replaced by an L&W product.
These seemingly out of place position light signals were installed in the late 1980's when the entire Tower 1 complex was re-signaled and I guess PL dwarfs were seen as distinctive for slow speed indications in otherwise color light territory, specially on gantry mounts.
