CN8832 Front End Damage.

CN8832 Rear End Damage.

One of the heaps of scrapped vehicles that formed during the clean up. For safety, two of the vehicles have their 4-way flashers on.

Most of the scrapped vehicles were put in dump trucks and hauled to the top of the incline where they were chopped up. Destroying them in place would have caused an environmental nightmare from the spilled oils and gasoline.

Railcars were mostly cut up near the bottom of the main incline and carted to the top of the hill.

One dangerous goods railcar containing acid leaked but it was near the east portal making disposal and clean up easier.

Please Read Before Using These Circuit Ideas

  The explanations for the circuits on these pages cannot hope to cover every situation on every layout. For this reason be prepared to do some experimenting to get the results you want. This is especially true of circuits such as the "Across Track Infrared Detection" circuits and any other circuit that relies on other than direct electronic inputs, such as switches.

  If you use any of these circuit ideas, ask your parts supplier for a copy of the manufacturers data sheets for any components that you have not used before. These sheets contain a wealth of data and circuit design information that no electronic or print article could approach and will save time and perhaps damage to the components themselves. These data sheets can often be found on the web site of the device manufacturers.

  Although the circuits are functional the pages are not meant to be full descriptions of each circuit but rather as guides for adapting them for use by others. If you have any questions or comments please send them to the email address on the Circuit Index page.
