I have written a V1.0 instruction manual on controlling an already installed and operational Interlocking for a single track shortline that has a level crossing (diamonds) across a two-main ABS/ATS Light Rail system.

The Light Rail line is protected by derails on either side of it on the single track shortline. One switch machine choosing a route to the diamonds or the other with a track leading to a bump-srop, and the other with a switch machine controlling a split-rail derail.

With the system at rest, the shortline has derails in the normal position allowing Light Rail unfettered access across the diamonds.

To have the shortline cross the diamonds, a call is made over the radio with DTMF codes to request the interlocking to give a stop indication to Light Rail, put the derails in reverse, and give a restricting indication to the shortline.

When the shortline movement is clear of the plant, the derails go normal protecting Light Rail, and they can cross the diamonds once again.

My question is, ....is this still considered an 'Automatic Interlocking' (GCOR 9.12.3)? A question came up today in class where someone said it was a manual Interlocking, but I made the comment, 'But it is controlled by a logical computer that takes a first-come, first-served call'. There are no humans controlling the switches, derails, and signals.

What would your consensus be on the name of this Interlocking?

And thank you for your input.

Starting cap for outside compressor only seems to last a year then I have to replace it. Granted, I only paid like $35 for it at a HVAC supply store, but c'mon. Could the cap be underrated to provide enough kick? Everything else about the pump runs fine, no over current or CB trips.

We live outside Portland Oregon, so temps shouldnt be that bad for it to last one year in its weatherized enclosure.

i always have two on hand because of this but its getting old.

Thanks for any suggestions.
