A National Roundhouse/turntable Inventory
(including some foreign countries)

(Inventory Organization)

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 
	as possible. 

   - 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 railroad point-of-interest.
