Russian R-1 Tram Abandoned

Hi Folks:

 Remember in 2014 news came out about a very futuristic Russian tram that was about to go into production.    I just found out (see link above) that the project in 2017 was abandoned because the tram would be very difficult to build and maintain because of its' layout.   Also for this new car, the current trucks {bogies?) would not work.  The Staten Island Ferris Wheel, also something new, seems to be also dead due to legal or financial reasons

It was a beautiful tram.   Shows that form and function do not always follow.  The car looked beautiful but would be very difficult to build and operate.   Good luck to the designers in the future. Some of us here in New York City would be happy if we were able to have a heritage trolley using old, Russian, or any other tram cars from somewhere in the world such as second hand equipment running a few hundred meters.  It does not look like it will happen.  If the Russian R-1 design was successful in being a good operating streetcar, many new communities would have taken a look at trams for city transit.

Good luck next time,

July 27, 1960: Last Day of Regular Electric Surface Transit in Brooklyn, N.Y.

The picture above was taken from the web site from their Trolleybus section.  This is a Brian Cudahy  picture from 1954 showing a Lorimer Street trackless trolley near the Myrtle Avenue El .  58 years ago service was stopped on the small ( 200 unit? ) trolleybus system for which mainly lasted ( most routes except Cortelyou Road) for only 12 years (1848-1960).

Today. chances are getting smaller for New York City to see a trolleybus system or a regular streetcar/light rail system.  Overhead technology is becoming obsolete and an "electric bus" does not require wires anymore.  Just a good battery or charging station.  Light rail, no way because it is expensive and will take away parking spaces.

I thought that trolleybus or light rail service will return to Brooklyn  in:

1961 because a report came out explaining about diesel bus pollution, but I was wrong.
I though that trolleybuses and streetcars might come back because of the 1960's environmental movement.  But I was wrong.

I though they would come back due to oil embargos in the 1970's and 1980's, but I was wrong.

I thought they would come back because of high oil prices, but I was wrong.
I thought they would come back because diesel bus fumes is the cause of lung diseases in Harlem and upper New York, but I was wrong.

I thought they would come back due to peak oil, but I was wrong.
I thought they would come back due to global warming, but I was wrong.
I thought they would come back to Second Avenue around 1992 because the MTA was interested in setting up a Select Bus Service using trolleybuses, but I was wrong.
I thought streetcars would come back on 42nd Street after various attemps, but was not signed off by the mayor.  But I was wrong.

I thought that streetcars would come back on the Brooklyn - Queens waterfront, but I was wrong.  Where will we park our cars and it is too expensive!

I guess I just was wrong!

Brooklyn Journey to Work by Streetcar: Part II: Including aggregate travel time in Minutes

In the previous map above, dealing with numbers of individuals using streetcar or trolley to get to work recently raises a question:   Do they mean bus instead of streetcar, or perhaps they do have long journeys to work and need to use the Newark Subway, or other light rail lines (Hudson-Bergen) or Philadelphia lines as well?  This would make for very long travel times.  Using "R",  I was able to bring in the American Community Survey of travel times in minutes, arranged by Census Tract.   A description of the material can be found in Census Reporter B08136_009 table that I brought in.
Through various steps, of converting the "R" data to an EXCEL file, geocoded it and brought it into ARCGIS,   I was able to add a new layer to my original map.   The B08136-009 table has a lot of "NA's", so I had to convert these to 0's so ARCGIS can use these values.  Sample of table produced from the ACS for Brooklyn is shown below:

My theory for this map is that streetcar usage should be tied with long trips.  In the legend, length of journey in minutes, I tried to show this by using stripes.  Only some polygons are showing using trolleys as a mode also having long travel times (stripes with an orange  background Census Tract).
The bottom line is that we cannot say that use of streetcars as a mode for today's Brooklynites is a  mistake, or one of the travel modes of Brooklynites that work in Newark and other cities in New Jersey or elsewhere.

Hi Folks:

    I came across a procedure for extracting data from the census using "R".  Interestingly, there is census data dealing with the journey to work.    There are table codes for this case and I used table prefix 08:  Journey to Work:  Worker's Characteristics: Commuting.  The code given in R by "RBloggers"  is able to extract a vast amount of statistics using the County variable.  Yes, Brooklyn has not had streetcars or trolleys since 1956 but look at the results in the map.   Are these Brooklynites  working in Jersey City or Newark New Jersey where there are streetcars?   Do they work or Phildadelphia or elsewhere?  Or did they missunderstand the question?  I am not sure.

The code for NY state is:
ny %>%
+ mutate(NAME = gsub(" County, ny", "", NAME)) %>%
+  ggplot(aes(x = estimate, y = reorder(NAME, estimate))) +
+   geom_errorbarh(aes(xmin = estimate - moe, xmax = estimate + moe)) +
+   geom_point(color = "red", size = 3) +
+   labs(title = "Journey to Work by Streetcar in New York State ACS",
+        subtitle = "2012-2016 American Community Survey",
+        y = "",
+        x = "ACS estimate (bars represent margin of error)")

> ## End(Not run)

And when run, see the  counties in NYS that  have streetcar ACP statistics: Lines are MOE's Margins of Error.

Beeswarm of Distances from Bedford Avenue Station Brooklyn to all other stations in NYC

In this experiment,  I took the data where I calculated the distance from the "L" train station in Williamsburgh Brooklyn to every other station (about 493 observations) in feet and read it into "R".
The mean distance is about 30,000 feet.  Using "R", I found out about "Beeswarm" program that is another way than looking at histograms.   The results is the interesting shape below.  Each circle is a distance to another station.  To download "Beeswarm", use this code:  install.packages('beeswarm') in the R environment.   Distance in Feet to next subway station for all stations to Bedford Avenue "L" train.

 Min.   :  2177
 1st Qu.: 15003
 Median : 25152
 Mean   : 30484
 3rd Qu.: 41862
 Max.   :110748

Traditional histogram

  One circle below represents the distance between the Bedford Avenue Station (index number 337 on a prior map) to the Lorimer Street station (index number 338) and the distance is 2176.9 feet, and so on.  This distance is probably at the bottom of the tree.  The distances at the top of the tree is perhaps in the --,---. range,  to the Bronx or Staten Island.  The mean is 34,800 feet.   The biggest distance is 110,748 feet or 21 miles.  To the Simpson Street Station in the Bronx (index number 18), the distance to Bedford Avenue in Brooklyn is 42,726 feet, or about 8 miles.  This is, of course, how the bird flies, not the street walk along distance or the subway track distance.  The top of the tree dot is the distance of 110,748 feet.  Notice that the largest distances, in this plot, are separated from their "pals", being that they are unique and probably is the distance to distant Staten Island Rapid Transit Stations.  On the bottom, the small distances to Bedford Avenue have "friends" nearby and are thus less isolated.

Nothing Much...

Hi Folks:

  Sorry that I did not add any new posts recently, but as far as New York City is concerned and the things that I enjoy,  perhaps you enjoy also, namely Light Rail for New York, subway expansion, trolleybuses, and so on, not is much happening.   I did come across these items, probably obtained recently in the subchat blog:

  •   The bus system of Philadelphia will be studied.  What is the genius's proposal recommendations?  Convert 15 -Girard streetcar to stink - a - roo bus!  What to do with the new PCC cars on Girard, convert 23 - Germantown to a historic streetcar.  This last item is not the planner's proposal but a writer.
  • In subchat, it was mentioned the when the "L"  train tunnel is under repair, there should be a return to express F train service in Brooklyn.  What will be the frequency?  Only three trains per hour.
  • In the Netherlands, and elsewhere in Europe, modified streetcars are being using for freight delivery.
  • Another trolleybus system may open in Turkey.
  • There are no concrete plans at the moment to expand subway services in New York, such as the Second Avenue subway to 125th Street or the Bronx.  There is some talk to expand the IRT Livonia Avenue Line to Linden Blvd via the shop but nothing concrete after many years.
  • I saw something in subchat that our beloved Church Avenue route in Brooklyn(B-35) will get articulated buses?
That's all folks!

Using ARCGIS Pro 3-D to get a picture of 39th Street Brooklyn

The map above was produced using ARCGIS Pro and a 3-D option and a multi-patch  file from the City of New York Department of information and technology. You are looking west at New Jersey from above 39th Street around Ninth Avenue and looking at the waterfront.  The red lines are subway trackways of the "D" West End Line subway line.   The line most to the left is probably revenue trackage of the line and the other red lines are storage and yard trackage, not really shown accurately.  If you look towards the horizon you can see the Statue of Liberty and parallel to this at the Brooklyn shore is 33 rd Street, the site of the Luchenbach disaster in 1956.  At the foot of 39th Street, at First Avenue, and a little to the north is the turn around loop for the Church Avenue Trolley.

More to follow.
