| These "END OF BLOCK" signs are ridiculous and a waste of tax payer money. A "block" is a section of track anywhere from a few hundred feet to several miles long. In normal operation only one train is allowed in a block. In signaled territory blocks are protected by block signals. Dispatcher issued "Track Warrants" give trains permission to occupy blocks in dark (no signals) territory. Blocks are often named. Say in the section of track there is a bridge over the DuPage River. The block might be called DuPage. Signs may read "BEGIN DUPAGE BLOCK" and "END DUPAGE BLOCK." But who deemed it necessary to put "END OF BLOCK" signs at the end of the stub station tracks? Isn't it obvious? Is this a FRA rule? OK, this is L.A. Maybe Metrolink engineers want to know if they can proceed and will call the dispatcher for permission if they don't get a signal. |
