    Serious question for the technically minded folks:

    how possible would it be to install a "simplified" CBTC system on the museum fleet that sends out its location so the system knows where it is and receives signals from it (almost like cab signaling) but doesn't include ATO, so that museum trains can continue to operate as more and more sections of track are cut over?

    It would still likely be quite expensive to retrofit any kind of CBTC equipment onto a SMEE. (That is why the R62/As and R68/As will not get the technology installed.) Only small sections of the system are currently using CBTC and the rollout of new sections is going very slow. (I would love it if the MTA could get their act together and speed up the roll out.) Also, the CBTC equipped sections all receive a new backup fixed block system that is currently used for work trains, and will likely be used for museum trains in the future.

    I do wonder if they finally figured out how to have the NTT have good braking performance in the rain/snow with the R211 fleet. All NTT fleets have poor braking in the rain. I wonder if the TA shop forces ever tried to "adjust" them.

    Another system (outside the country) used to have a "rain mode" on all their trains that improved performance in rain but slightly reduced acceleration and brake rates. The mode would also occasionally disable dynamic brakes.

    Foamers can easily pass the exam and get an TA job like anyone else. Just because an buff work for the MTA doesn't mean your overzealous love for transit goes away, JMO.

    Should railfans even be able to work for the TA? Banning them from working there would weed out many non-serious job candidates.
