[PRCo] MIT MR

[Jim Holland]

Most of the way down on the page http://www.nmra.org/ is info on an MR 
at MIT which includes TrolleyCars!~!~!     While this is HO, any scale 
can receive inspiration and ideas from this layout.    What is Truly 
Fascinating is the Huge Structures used for the downtown section!~!~!

The *Webmaster's Choice* is not just a random pick of available web 
sites. We look for sites being well laid out, reasonably quick to load, 
and most of all, with good content. When you load the page, you should 
know you are in for an enjoyable time that will extend beyond the 
homepage. Content is what makes a site excellent as opposed to just 
good. This may include a good mix of graphics and text put together in 
an interesting, informative and perhaps even entertaining way.

          *The Tech Model Railroad Club of the * *Massachusetts
          Institute of Technology*



We are featuring the website of The Tech Model Railroad Club of the 
Massachusetts Technology <http://tmrc.mit.edu/>. The TMRC 
<http://tmrc.mit.edu/>, was founded during the 1946-1947 school year and 
is one of the oldest model railroad clubs in the United States. The TMRC 
<http://tmrc.mit.edu/> has many areas of interest including a permanent 
HO scale layout, the fictional Tech Nickel Plate Railroad, the MITCo 
trolley line, their custom made control system, the System 3 
<http://tmrc.mit.edu/sys3/>, videos made with their camera cars as well 
as many construction, scenery and layout photos.

You will find many interesting features at The TMRC 
<http://tmrc.mit.edu/> website is the information regarding their custom 
designed and built control system, the System 3 
<http://tmrc.mit.edu/sys3/>. As they describe it "... / is fully 
computer controlled through a network of circuit boards designed by club 
members. Rather than a single large control system, components of System 
3 are distributed under the layout. Microcontroller based boards called 
block cards control up to eight blocks of track, while a second set of 
cards, called switch cards control up to eight turnouts apiece. These 
cards all communicate with a server program running on a computer. A 
separate program presents a graphical display of the state of the 
layout." /The current system is a descendant, if you will, from the 
first control system built in 1954. It was one on the first automatic 
control system for model railroads that was ever built.
