A National Roundhouse/turntable Inventory
(including some foreign countries)
Our image names are organized in the following manner:
- The State abbreviation is the first two characters.
- The next set of characters is a city/town name.
- The next is a numeric indicating the number for
roundhouse/turntable found at this location.
- The next set of characters is "optional" and may
or may not be present. These characters
indicate the road name. As we get more time
we will fill in this field for as many sites
- The next set of characters is the viewing system
used to acquire the image. (If not present,
Google Earth is assumed.) Other imaging
systems that we use include:
MSN - Maps and Directions(Virtual Earth)
Terra - Terraserver
TNM - The National Map.
- The next set of characters are optional, as
indicated by the word "Special", and is
provided if we were able to capture a MSN
perspective image. Usually these perspective
images have great resolution plus with an
angle view point side details are revealed.
- Sometimes we include more than one perspective
image for a particular site. In this case,
we then tag the image with a numeric after
the word "Special". We use "Special"
to provide difference scales (zoom).
(Currently we a converting some of these
to the below "Sp" designation.)
- Sometimes instead of using "Special" we will
use "Sp" with a cardinal direction.
For example, "SpN' meaning MSN perspective
image looking "towards" the North. We
provide all the cardinal directions that
are available, i.e, N-E-W-S. We
use "Sp" to portray direction.
As an example on the first page, ILJoliet1, the image is of a
Roundhouse/turntable located at Joliet Illinois. This is the
first roundhouse/turntable we have located at Joliet, thus
the number "1" at then end of the city name. We have
not decided on a road name yet, thus no road name is present
(maybe we will identify a road name when we have more time to
research). And the image
originally came from Google Earth, i.e., the default of no
imaging system name present. Using this naming convention,
you can easily go to the State of your choice and look for
your favorite city.
In addition we have several directories We have also started an
inventory for several counties as indicated
by the directories named after a particular country. Another directory
entitled "other" is where we have placed some interesting images that are
in question as to what they actually are or have some other associated
