Wellington's Trolleybuses also end on October 31, - November 1 - 2017

On 31.10.2017 the trolleybuses drove on Wellington's streets for the last time. A total of 29 trolleybuses were used on the last day of operation on lines 1, 2, 3, 7, 9 and 10. The wagons 387, 383 and 384 moved in as the last three trolleybuses, behind car 384 the gates for the trolleybuses closed forever at 0:45 am on 1.11.2017. ... more

It is funny that Wellington lost it's trollebuses on October 31 61 years after Brooklyn lost its trams and the Cortelyou Rd trolleybus.

News note above comes from Trolleymotion.

Experiments with Trolley Trucks Continue in Los Angeles California



See the link below:
https://cleantechnica.com/2017/11/12/siemens-ehighway-heavy-duty-trucks-continue-california/


The experimental Los Angeles - Long Beach trolley truck line was presented before the public last week and will be tested during the coming year.   Many organizations are involved, including the Los Angeles MTA.  I wish them success and perhaps having an overhead over a highway we make people who make decisions re-look at interurban trolleybus applications.  Local trolleybus new starts are little and some big users of trolleybuses are considering or already abandoned their systems (for example, Philadelphia, Moscow, Wellington...).

To be continued.

Data Scrapping for Transportation Info using "R"

Recently, I was exposed to data mining and data scrapping using "R" which is a statistical relating language which has geospatial capability.   In a recent "R" blog, it was shown how to use "R" to data scrape the US census information from the "American Community Survey" for 2015.  I found one variable that is transit related and it is labeled "PublicTrans".  I do not know what it measures but you are able to bring it up for selected cities using code.  There are over 500 variables dealing with the census and it is a nice resource to know about.  Some code is shown below.  More to follow.
