In ordinary operation, North Shore and CA&E cars are limited by law to full series, with a top speed of 35 or 40 MPH, which is probably about what the South Shore cars will do in full parallel. The difference is that with proper authorization and the right circumstances, NS or CA&E cars can still reach their design speed of 70 MPH or so. The South Shore cars can't.Randall Hickshttps://www.blogger.com/profile/16246581917018679919noreply@blogger.comtag:blogger.com,1999:blog-1810478746663531557.post-32825924790207784812016-08-20T08:20:50.750-05:002016-08-20T08:20:50.750-05:00I think the idea of "running in parallel"...I think the idea of "running in parallel" works some people up a bit. But from the standpoint of motor voltage, there's no big difference between running a South Shore car with its permanent series-paired motors in parallel, and running a North Shore car with its permanent parallel-paired motors in series, other than the 25% between 600 and 750. In each case, each motor sees 300 volts.<br /><br />R. W.

The South Shore cars have 750V motors in permanent series pairs, so each motor sees 300V when operating in full parallel, or two-fifths of the design voltage. That, however, is fast enough for our needs.Randall Hickshttps://www.blogger.com/profile/16246581917018679919noreply@blogger.comtag:blogger.com,1999:blog-1810478746663531557.post-12511377607043199042016-08-19T21:54:05.668-05:002016-08-19T21:54:05.668-05:00Does that mean you run the South Shore cars in ful...Does that mean you run the South Shore cars in full parallel at the museum to obtain half speed?Anonymoushttps://www.blogger.com/profile/10636463043670835798noreply@blogger.comtag:blogger.com,1999:blog-1810478746663531557.post-77488005002586361242016-08-19T10:24:29.442-05:002016-08-19T10:24:29.442-05:00I think the correct way to describe it is that the...I think the correct way to describe it is that there is an MG set to convert 1200V to 600V for the auxiliaries, such as the compressor, and the control system. This would be bypassed when running on 600V, and we won't need to use it. The motor circuits are designed just for 1200V, and on 600V it can only go at half speed, in much the same way as our South Shore and IC cars. But that will be fine.<br /><br />Oh, and yes, that carpet was a real luxury.

The option for 600v as designed is great. Is this newer news? Looks like you had a nice carpet to lounge on while you did this electrical engineering work.Anonymousnoreply@blogger.com
