The P2s on the cabcars are now roof-mounted & operating at full PSI, and sound much louder & clearer.
On the other hand, with the F40s, their K5LAs had their 1, 4A & 5 bells removed, & were reversed in 2001.
Well, now they've turned them forwards again, and are using these K2s consisting of the 2 & 3A bells.
They sound a dischord, and aren't as pleasant as the new P2s.
Hopefully, Metrolink is next!
