"Type 6"

Postby Arborwayfan » Wed Jun 17, 2015 1:33 pm

Type 5
PCC (various versions)
Type 6 (never built; Boeings instead)
Boeing LRV
Type 7
Type 8

Did the T only assign type numbers to equipment it designed itself? Or was there some other reason for not numbering the various PCCs, the Boeings, and IIRC the Center Entrance Cars?

That's pretty much the reason. The PCCs and Boeings were essentially off-the-shelf models designed by other groups, with minor changes made for the T or its predecessors. The various Type X cars were all either designed in-house or were custom designs built to the T's specs.

Don't forget the ever elusive Type 7.5's with their black flooring!

The Type 6 mockup is at the Seashore Trolley Museum, in Riverside Barn on "Track Zero."

The 'type' terminology originally applied to 'semi-convertable' cars custom made from specs set by the Boston Elevated, which is why the non-semi-convertable centre-entrance cars aren't included in the series. After the Type 5 it's pretty much applied to any Boston streetcar built to spec.

In reality, the 'Type' cars were double-ended cars with doors at the ends. Car 5000, never assigned a Type number started the series off. Unable to get cars built to 5000's design, the Elevated ordered 40 off-the-shelf cars from Brill; these became the Type 1s. Fifty Type 2s from Brill and one-hundred Type 3s from St. Louis followed, all virtual twins of 5000. Fifty Type 4s, ordered in 1911, featured drop platforms for faster boarding, and prepayment fare collection. 225 additional cars, dubbed 4A, 4A2 and 4A3 were added to this fleet. Ten additional cars, Type 4 in appearance but Type 2 mechanically brought the number series to 5475. No cars carried numbers 5476 to 5499, but a new series started at 5500 and continued to 5970. These cars, based on Charles Birney's lightweight design, became known as the Type 5s. The planned replacements for the PCCs, based on rapid transit designs, but using the Type 5s' dimensions, was designated Type 6.

It should end there!

During the teens, the Elevated had the Laconia Car Co. build entrance bodies used to join two smaller carbodies into longer cars. These were designated as No. 1 to No. 4 articulated cars, based on which order of center section was used. They were numbered 4000 to 4067, and used cars with 20 foot bodies. Over 100 additional cars were built using 25' bodies, numbered in the 4200s and 4300s and designated Nos. 5, 6, 7, and 8 Articulateds, again based on the orders of center sections. No further articulated cars were built or ordered until 1976, when the Boing LRVs arrived. These should have been designated No. 9 Articulateds. The 120 cars ordered from Kinki-Sharyo should have been designated No. 10 Articulateds, but were instead designated Type 7. The Type 8 and 9 cars thus follow.

The next stop is Washington. Change for Forest Hills Trains on the Winter St. Platform, and Everett Trains on the Summer St. Platform. This is an Ashmont train, change for Braintree at Columbia.
