The "Mission" of this site is to provide some useful information about electronics and electronic circuits to model railroaders and others in general.
There a number of sites on the web that have copied, en toto, my pages to their sites. If you are not certain you are looking at the latest version of a page, scroll to the very bottom and check the revised date. Also, every diagram will have a date near the title along with the original files name.
Automatic Reversing Circuit - January, 2017
The "Mission" of this site is to provide some useful information about electronics and electronic circuits to model railroaders and others in general.
Welcome to a page of electronic circuits that are mostly for model railroads. Shown are circuits that were developed to solve certain problems or achieve a desired control function. There are throttle, train detection, animation, control and general purpose circuits on this page.
Following this section is a list of the circuits that appear on these pages. Select one of the internal page links or scroll down the page until you find something of interest.
The link under the paragraphs in each section will take you to the document from which the text is taken. These documents will provide more detaißled explanations and schematics for the circuits.
The circuits listed in the index sections appear in no particular order but have been loosely grouped by the type of function they perform. The Numbers to the left of the index listings are arbitrary. There is also a "Miscellaneous Items Index" that features circuits that may not be model railroad related and non electronics related pages.
The circuits on this site are purposely designed to be as simple and efficient as possible. In most cases, they perform only one function, but do it well.
While the circuits are easy to connect, good wire management should be used. A neat looking circuit is likely to work better than a messy one.
Most of the circuits require a DC supply. An incorrect power supply polarity will damage these circuits. P>
The circuits use parts that are widely available and easy use. Some of the circuits use devices such as Hall Effect sensors but even these are used in a simple manner.
Some circuits and pages don't have a particular use and are only meant to be educational or informative.
Some of the circuits are of general interest, generally mine, and may be of little use. They are functional however and at the very least, a useful waste of my time.
Some of the circuits on this site, in their original form, are or were in use by the London Model Railroad Group. This large, 'O' Scale club layout is located at 4474 Blakie Rd. Unit 127, London, Ontario, Canada. Public viewing nights are the first Tuesday of the month from October to May.
I am not an electronics professional, although I play one on the web, and only design these circuits as a hobby.
Therefore I can make no claims to the quality or usefulness of the circuits shown on this page. They should however work as stated and will not be dangerous to persons or property when used in their intended manner.
If you see any problems with the circuits or have any questions or suggestions please let me know.
If this is your first visit to this site, please read the sections above for general information about the site. Thank you.
