Latvia Carve Stream Map Using GRASS 6.4.1.

In the map below, I used GRASS 6.4.1 and its' Hydrology program to create the attached map.  Instead of using existing streams as an input, I used Latvian Railways.  Roads are also shown on the map.  I believe that the bright yellow areas appearing near railroads are those areas that are in danger of flooding in a strong storm.  I do not work in this field and I am just experimenting with the software.  No decisions should be made using this map.  The software is a great learning tool

NYC Transit Authority Plans to Convert "Sea" Beach Line (N) to Trolleyboat

http://rosetintedvisor.tumblr.com/post/34623407509/the-river-that-was-the-n-train

  As a result of Hurricane Sandy, the transit authority is still unable to provide Sea Beach Line Service between 59th Street in Brooklyn and Coney Island due to flooding in the open cut, specially between 86th Street and Avenue U stations.  As a result of failure to pump out the water, the New York City Transit Authority will convert the section from 86th Street to Avenue U to TROLLEYBOAT.  The line has already the "Sea" as part of the name.  See picture below to see an early model of a trolley boat.  In keeping with tradition, the much beloved Type D Triplex cars (shown below from a picture taken from the web showning a train at the Beverely Road Station on Brighton Line) design will be copied.  Three unit articulated boats with circular passenger connecting passageways will be built.  The units will receive their power by way of trolleybus wires.  For many years, the Type D Triplex was used on the Sea Beach and some of the other Southern Division lines
