Some Comments about Various Topics

Hi Folks:

 No  so much has been going on in the New York City regarding the topics mentioned here in this blog.  Regarding Route 15 Girard Avenue in Philadelphia, I found out the the reconstructed PCC cars running there  are 15 years old and that parts are wearing out.  The parts are unique and are hard to replace.  This may give SEPTA the excuse to pull the plug.  If standardized cars are ordered from a manufacturer, the problem of parts become less problematic.  Regarding in motion charging for trolleybuses and battery buses in cold environments,   I read today in subchat that the recovery time to recharge a battery bus in cold weather is much longer than in warm weather.  If a transit authority orders pure battery buses and in cold weather recovery time is longer, more buses are required and it becomes inefficient.  Of course, trolleybuses do not have this problem  It would be ironic that the battery buses replacing the trolley coaches in south Philadelphia could not function as well.  I believe the remaining trackless trolley lines in north Philadelphia are also in danger.   There does not seem to be an idea in the transit management field world wide that trolleybuses with in motion charging is superior to pure battery buses.   I do not see many brand new in motion trolleybus systems being established.   What happened to planned systems in Montreal Canada and Spokane, Washington?


A reader asked if CAD files can be used in making climate maps.  I never worked with CAD files before but in ARCGIS mapping programs,  geo-referencing another map into an target map,  CAD files can be used, according to their literature.
