Posted by randyo on Sun May 18 19:21:46 2008, in response to Re: Question about cineston controller, posted by Jeff H. on Sun May 18 00:38:21 2008. I believe that the term "Cineston" is copyrigted to WABCO even though the BMT Bluebird, which was equipped with the first controller of this type, had a similar controller manufactured by GE. I have the matching controller from 8000 to the one you have at Branford, by the way. Interestingly enough, even though the Bluebird's controllers were manufactured by GE, I have an instruction manual from WABCO for an "electro - pneumatic brake system for articulated rapid transit cars with cineston controller" which from all indications seems to be for the Bluebird. I haven't heard of any other articulated rapid transit cars using an electro -pneumatic PCC type of brake system other than the Bluebird since the Chicago artics were all electric. Also the description of the brake system having spring applied and air released brake shoes in the WABCO book is consistent with the type of braking system on the Bluebird. It could be possible that there was some collaboration between the manufacturers at the time that allowed for the mixing of parts. Jim Greller's book on BMT equipment also seems to indicate that the controllers on 8000 were slightly different from those on the later units and that these were changed to match those on the later units. The reason for that might have been that although 8000 as delivered lacked H type drawheads, the unit apparently received them at some point during its service history since the book has a photo of 8000 in CIYd and it clearly has an H drawhead. The only question that I have is which controllers from 8000 do we have, the originals or the replacements? |
