Maybe the Mattapan line could be (re)connected to the Green Line, probably by way of Arborway to Heath St. and then the color would make sense and a lot of folks will be happy.

In retrospect, if the Green Line had been designated the Orange Line and the Red Line been designated the Blue Line (remember the 01400 series cars), would the amount of repainting of equipment to match have been much less?

Well, as I recall reading, the original Cambridge Seven design didn't have the cars painted for line colors, but instead in a uniform grey scheme- there are a few pictures of PCCs and Orange Line trains painted that way on the nycsubway website.

There was a crew installing the maps at Cedar Grove today. The Mattapan Line was in red.

Things seem to be getting better service-wise. Tonight's rush hour service was up to 4 cars, 3268, 3234, 3238 and 3254. That makes 7 cars seen or reported in service to date though there seems to be some disagreement whether it was 3262 or 3263 which derailed on Saturday. Except for that report, the latter hasn't been seen.

On another rail fan website I have seen a picture (not mine) of # 3262 derailed at Mattapan. It also shows the Green Line Response truck and about 15 people came over from Riverside to try to rerail 3262.

Other pictures reveal # 3230, Out of Service, as well as another PCC in the facilities at Mattapan being looked over

The derailed PCC was 3262 and PCC 3254 was used in pulling the derailed unit back on to the tracks. Here are some of the photos I took:

Now I have a question. The PCCs on the High Speed Line were once MU capable but now they have be De-MUed. Did they rework the controllers making it permanent or just pull the contact pins on the couplers? Not a question of high passenger volume but more an issue of pulling or pushing a disabled PCCs.

If I'm not mistaken the person who ran the inital PCC rebuild in 99 told me that when they overhauled the cars before the rebuild they had the mu equipment removed back then and could not replace it. But John or Gerry can Chime in on this because my memory of some things are clouded.

Except for 3265 (the first car done) the coupler blocks and hoses were left off the cars but they are otherwise unchanged. In the prior rebuild (1977-1983) the drum brakes were replaced with tread brakes but the control systems weren't modified to match, so there is a small time gap after the dynamics cut out before the brakes take hold. Mechanically and electrically the cars are still MU cars. True single units are a totally different animal. (For examplr the master controller is behind the front truck instead of under the operator's seat. When the cars went for the rebuild, the cutout levers may have been removed, and the 14 wire in the rear cutout and the 14 and 5 wires in the front cutout may have been jumpered toimprove reliability of the door interlock and rate circuits. Interestingly circuit 12 was jumpered at all times, whether or not the sticks were in, so the chimes always worked on a dead tow. Not so any more.

Since I reference these, here is the full circuit list.

1 Power On
2 Forward
3 Reverse
4 Accellerate
5 Rate Control
6 Coast (Brake Off)
7 Reset
8 Track Brake Relay
9 Grounf (Labeled 0)
10 Track Brake Contactor
11 MG Alarm (On if a MG contactor in train is out)
12 Passenger SignalChime (Rings in all cars)
13 Conductor Signal (Single Stroke Bell)(Rings only in next car up)
14 DoorInterlocl Circuit

(All Electrics had 6 more MU circuits (15-20). I know two were for the Emergency Brake and 2 were for the friction brake. If someone really wants toknow I will look them up on the other computer.)

Sunday's cars were 3234 and 3254. (I wonder if today's culprit was 3234 again?) Will observe the PM "rush" and post the cars in service. All hell breaks loose on Wednesday - the first "REAL" rush hours!

It turns out that the Green Line was running on a Saturday Schedule today, thus Mattapan was scheduled for 3 cars on an 8 minute headway all day. Red Line service was normal weekday headways, so there were plenty of passengers waiting at Ashmont. Some time later, 3268 rolled in being pushed by 3262, followed closely by 3234. After that 3234 made a trip by itself before being rejoined by 3262. That works out to 2 cars in service outof 3 scheduled.
