TOMC on the 7 train for the Mets opener

How is the nostalgia ride on the Train of Many Colors supposed to work for the Mets home opener now that CBTC is on the Flushing Line? Is there going to be some sort of portable transponder? I don't think they've done it in 7 years.

Is this going to become a thing they can do more often? Will they also be able to have nostalgia trips on the Canarsie and Queens Blvd lines?

I hope they include the pair of R36MLs they added to the consist. My understanding is that they're identical to the R33ML except that the lights blink like on the WFs. Or are there other differences too? Also it would be nice if it's not just the ex-Redbirds, but also some of the older SMEEs like the R-12 and R-17.
