My Comment:

     Mexico City's trolleybus system has not been in the news recently.  It was formerly one of the largest systems in North America but it's fleet size was dropping.   It is interesting that the mayor appears to be pro trolleybus.    I also know that Mexico City has air pollution problems.  It is not clear if these Chinese made trolleybuses have In Motion Charging.

Re Philadelphia:

    I Googled Map Philadelphia for "Snyder Avenue" and along that avenue,  at least for the sections that I looked at, the trolleybus wire overhead is gone, but the trolley sport poles (many of them seem in place.  Also for Tasker Avenue in South Philly, the wire is gone but some support poles remain.

Germany may be Planning to convert 631 Miles of the Autobahn for Trolley Truck Use

Hi Folks:

   I saw this today.  The ongoing experiment in Germany with trolleytrucks will last until 2022. If successful, and if money is available, many miles of road will be converted,     I believe it was mentioned in the article that the overhead may be used by other vehicles for charging (in motion charging).   This would imply that a smaller truck with batteries if equipped with overhead can use the overhead for a charge and then leave the highway and proceed a long way without wires.  How about interurban service using trolleybuses as well?   But I think the overhead will need to be redesigned for use by trolley buses and trolley trucks.

From International Business Times:  Wesley Dockey, 5/14/19

DW reported that Germany could be planning to convert 1,000 kilometers (621 miles) of its 13,000 (8,077) Autobahn highway system into electric highways for hybrid trucks.

New Developments from St. Petersburgh, Russia

Hi Friends:
A Russian friend of mine gave me the link below to tramway developments in his home city of St. Petersburg.   He is an observer of the transit scene there for many years and he was worried that trams were being removed from his beloved city.  His link to, in Russian, show the construction of a completely new line, thus giving hope of new developments.   Also, there are great pictures of new tram cars in various settings.

  I told Igor that he is much to be proud of in St. Petersburg regarding trams.  Least they and trolleybus continue to exist.  In my home city of New York, the trolleybuses died in July 1960 and streetcars on October 31,1956 and in 1957.  This was a long time ago.  A large generation of New Yorkers who are not foreign born or who come from US cities that have streetcars, have no idea what a trolleybus or tram is.  Nice videos attached to the site as well.
