Here is the story as it was told to me by someone who was involved with the operation which was classified as a Level 3 Emergency by Amtrak.
At about 9:00pm, a Delmarva Power transmission line fell across all three tracks around the area of Churchman's Crossing (Milepost 36.9), north of Newark, DE. All trains were held at major stations, except 188 who had already departed Baltimore. 188 was stopped just north of Perryville, MD at 9:23 pm. The plan was to couple the last MARC train of the evening to 188 in order to get a cab car on the reverse end of 188 so that it could then be driven back to Baltimore. The MARC train waited for 188 to arrive and by the time they coupled up (12:20 am), the MARC crew was unable to run the train as they had reached their hours of service limit. Plan B was then for 188's engineer to run the train back to Baltimore, but when the time arrived engineer informed CTEC that he was not qualified on MARC equipment. At this time Tracks 1 and 2 were getting ready to accept trains at the site of the downed power line so Plan C was to uncouple Train 188 from the MARC train and have it proceed north, but before that could happen Train 188's crew reached their hours of service limit. To fix this new problem 198 departed Baltimore and dropped a relief crew off for 188. A bunch of other crews were beginning to run short on time and arrangements were being made to get them relief crews as well.
Tracks 1 and 2 were back in service about 1:00am, but at CTEC there were Track Occupancy Lights (TOL) on all the tracks near the site of the downed power line, possibly due to blown track circuit fuses. Unfortunately, the TOL's were running right through RAGAN interlocking (south of Wilmington) which locked out the switches in the plant so CTEC could only use No. 2 track through the area.
Southbound Train 55 was the first train through the affected area at 2:00am and by rule it had to run under signal indication, which were all stop and proceeds. Train 188 was re-crewed and departed Perryville at 2:10am and once 55 cleared the block, 188 was given a form D to operate under DCS rules northbound through the affected area to Wilmington. When 188 arrived in Wilmington, the power director did a "signal flip" from Wilmington to Lamokin, near Chester. I don't know exactly what this is, but it removed all signal power for a brief period of time. The intention of this signal flip was to attempt to clear the TOL's between Wilmington and DAVIS Interlocking near Newark DE. Somehow this "signal flip" went bad, and signal power was unable to be restored. This basically left no signals between Davis and Chester.
Now, 188 had just arrived in Wilmington. To get north, they had to run at restricted speed (with Rule 241s at every interlocking) up to Chester, since he was the first train to operate through that area. These TOL's also left it impossible to line routes for the southbound trains, as the route was lined for northbound trains. At about 4:00am, a C&S maintainer arrived at YARD interlocking, just south of Wilmington, north of RAGAN, to manually crank a switch (GRS model electric) there so CTEC could run southbound trains. All problems were resolved by 6:30AM.
