[quote]QUOTE: Originally posted by mackb4 trainjunky29 that's wild,I couldn't imagine getting a track warrant for signaled territory.Whats the purpose of a signal or the reliance of it?We have track time form 23a's that give us permission to go in boths directions on a outlined point a to b track.But that is still in signaled territory and all signal rules still comply.The maintance of way uses the 23a's to occupy track to do work.And then on the back side of the form is an area for the (mow) person who got the permitt to allow joint occupancy with other(mow) people.Gets real complicated at times. [/quote] Dear Mack, Block signals serve three purposes: operate trains more safely, keep the flagman from having to walk back for flag protection, and allowing trains to operate closer together on high speed lines. Block signals will, of course, not control train movements. You need some system to tell trains how to go where when. Otherwise, within a few hours, your railroad will be inching along at restricted speed past stop and proceed signals. A timetable can efficiently move trains, a track warrant can, or DTC can, but something is needed whether there are signals or not--CTC excepted, of course. Sincerely, Daniel Parks
