• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

It is a jumper cable that is attatched to both rails...

It indicates to an automatic signaling system that there is something in the block ahead.

It will drop cab signals and wayside signals

For those who know, I have read that a shunting device is put into place when a work crew is in a block. What is a shunting device and how does it work?
The rule used to only apply in ABS/TWC territory. I have never seen a rule where it is required in CTC.

I'm not familiar with MOW rules so idk where its required.... I could see where it would not be required as protection in CTC could be provided by the dispatcher.

The reason that I asked this is because of an ruling the I saw on the National Transportation Safety Board regarding an accident. Apparently there was work in a rail yard and a train entered the work area killing several workers. The ruling was that there was no shunting device in place and the striking train had a clear signal. Thanks for the explainations.
