19 EAST, COPY 2. Transport Blog connects to Photon Courier's commentary on the effect of the Internet worms on CSX Transportation's dispatching. Transport Blog correctly notes that railroads using sufficiently advanced technology to be affected by a computer virus is a good thing (I think there's a dig at the socialist railways that have yet to adopt the Armour Yellow and the SD90AC in there.) Yes, But. The old methods sufficed to move trains over dark (unsignalled) territory with few open stations. Will the U.S. railroads have in place procedures to substitute track warrant control as a backstop to the centralized traffic control installations, in order that trains keep moving despite computer failures. Late, but moving, is less frustrating than standing still.
