230 was already sent to West Farms to train their operators, so that theory is out the window.
And, BTW, 947 was being sent to Zerega or just leaving Zerega because that's the correct route from JG on the Bruckner Exp. (or Blvd.); either way, it passed the streets that would've routed it to West Farms, anyway. There's usually a C40LF departing from JG every morning to head into Zerega for training purposes, FYI... usually operated by an Superintendent.
