How can a freight train "lose" its brakes? The only ways I can think of are if someone closes an angle cock near the head-end after the brakes have released; OR in a long down grade with NO operable dynamic and no way to pressurize the train without releasing the brakes--bringing the brake pipe pressure down to zero. The article I read said they knew the brakes had already failed when they were at the summit of Cajon Pass. What possible reason could the brakes have "failed?" * Replies: 4111, 4112 #: 4111 S1/General 14-May-89 01:44:28 Sb: #4095-San Berdoo Wreck--How?

No word yet about the others or the remainder of the train. NTSB news conference this evening. I'll post any real information. ...Keir #: 4112 S1/General 14-May-89 02:13:07 Sb: #4095-#San Berdoo Wreck--How? Fm: Keir Jones 71160,2217 To: Ed Warren 71251,2705 (X) The NTSB release, based on data recorders and on-site observation, stated that the brakes were working normally 10 1/2 miles before the crash. 8 miles before the crash the brakes were put into "emergency." The brakes were still hot to the touch this afternoon. They are currently investigating the possibility of overloading. The specified tonnage would fill each car approx. 2/3 full, but some reports from witnesses (whether to the loading, en route, or at the crash was unstated) indicate that the load was above the sides of the cars. This is a preliminary report and is subject to revision as more information becomes available. ...Keir * Reply: 4113 #: 4113 S1/General 14-May-89 02:39:55 Sb: #4112-#San Berdoo Wreck--How?

This particular wreck has gotten a lot of the wrong kind of publicity for the SP, and those of us who are SP freaks are definitely interested. Everything on a Flanged Wheel!

The news reports I've heard have been talking about SP's safety record, and relaying NTSB's statement that SP has a good overall record. They're talking as if it's simply the kind of horrible accident that can happen to anyone. One reporter compared it to houses next to a freeway or under an aircraft approach path. Even the people in the neighborhood seem to regard it as a tragic accident rather than the inevitable result of ongoing negligence. Nobody responsible has even implied ongoing negligence. ...Keir #: 4158 S1/General 15-May-89 02:56:59 Sb: #4113-San Berdoo Wreck--How?

This sounds like a red herring, but the NTSB announced the results of its investigation into the safety records of the train crew. Engineer Holland was cited for excessive speed March 31, 1986, and was cited for failure to properly connect the brake lines between multiple-unit locomotives February 13, 1988. Brakeman Reese was cited for failure to take action regarding excessive speed. (No date given) None of these citations involved accidents. On the highway a record like that would qualify a person for good-driver discounts. A third data recorder was also recovered today, but the information has not yet been released. Investigation into the possibility of mechanical failure is continuing. Engineer Holland is suffering from a collapsed lung, and took a turn for the worse today. His condition is listed as critical. ...Keir #: 4212 S1/General 17-May-89 03:07:56 Sb: #4113-#San Berdoo Wreck--How?

SP came in for praise from the City Council and City Attorney today. It seems SP made an offer that was better than they expected to achieve in court. SP is buying the 11 houses and making a greenbelt out of the area. The city will maintain the landscaping. SP also took full responsibility for the crash, and for any future accidents which could occur at the same location. The Red Cross shelter was unnecessary, as SP provided hotel accomodations for those rendered temporarily homeless, and is making an effort to compensate them for their losses. That kind of corporate action makes me proud to live in SP territory. ...Keir * Reply: 4213 #: 4213 S1/General 17-May-89 03:34:52 Sb: #4212-San Berdoo Wreck--How? Fm: Dorr Altizer, Sysop 76702,402 To: Keir Jones 71160,2217 Sounds like one of the better endings to what is usually a long story of court battles, media hype, etc. Maybe SP is trying to return to the days when the public relations department had offices above the basement. Or maybe their new boss has made some changes, behind the scenes. None of the news will make it on national television, tho, since it's not bad news. Sigh. Do you know if any FRA people were involved in the settlement? Or did SP negotiate with the city directly? Everything on a Flanged Wheel!

The train was overloaded by 2600 tons. The amount of potash was estimated during loading. Nothing was actually weighed or measured, and they have apparently scraped up a lot more than the train was supposed to be carrying. ...Keir * Reply: 4306 #: 4306 S1/General 23-May-89 01:25:37 Sb: #4282-San Berdoo Wreck--How? Fm: Robert I. Wright 74776,374 To: Keir Jones 71160,2217 Perhaps you can answer some questions about the wreck for me. It is puzzling why the train lost it's brakes and was unable to stop. I understand that the dynamic brakes were inoperative on two of the locomotives, but wouldn't there be enough reserve braking power to stop the train? Any what about the air brakes? It is my understanding that every car has a set of air powered shoe brakes that are more than sufficient to stop each individual car, even if it is fully loaded, and that these brakes can be applied along the length of the train by the engineer. Are these the brakes that are refered to as "emergency brakes" by the media? Even if it was overloaded, I do not see what could have gone wrong. Were both braking systems inoperative or do I have some misunderstanding of the braking systems on trains? (Feel free to instruct, what I have laid out here is about the limit of my understanding). #: 4325 S1/General 24-May-89 02:25:18 Sb: #4306-San Berdoo Wreck--How? Fm: Keir Jones 71160,2217 To: Robert I. Wright 74776,374 (X) According to NTSB, the train was severely overloaded. This can cause the brakes to fade and lose their effectiveness, even in an emergency application. The air brakes were on hard enough to score the wheels, but excess weight was just too much. The dynamic brakes are simply a system for using the traction motors to help slow a train. They are actually an auxiliary system, and not all locomotives are so equipped (although most are.) On level ground, or properly loaded, the brakes would have been quite adequate. Overloaded, downhill, adequate brakes probably don't exist. ...Keir #: 4360 S1/General 26-May-89 02:51:10 Sb: #4347-San Berdoo Wreck--How? Fm: Keir Jones 71160,2217 To: Robert I. Wright 74776,374 I don't know the exact grade, but Cajon Pass into LA is indeed steep. The highway is a great spot for runaways (and one joker who was cited for 70+ mph on a skateboard). BTW, the wreck location had another disaster today. A Cal-Neva gasoline pipeline ruptured at the wreck site. It had been inspected after removal of the wreckage and was brought back to full pressure today. It sprayed flaming unleaded over the homes around the wreck site. ..Keir #: 4383 S1/General 27-May-89 02:51:15 Sb: #4347-#San Berdoo Wreck--How? Fm: Dennis Larson 75555,705 To: Robert I. Wright 74776,374 (X) Actually, on mountain grades the safety factor is reduced greatly in trucks, trains and automobiles. The problem is that gravity is always pulling constantly. Truckers have highway warning signs in these areas so they won't overheat their brakes. Have tagged along with Rio Grande brakeman on the hilly CZ route and they are conducting running air brake test all the time. I suspect before the beginning of a long down grade. Next time when driving drag on your brakes, hold down on the gas pedal. Your brakes will be gone inside of a minute or two. Consider a train going downgrade for miles and miles. A leaky train line which could mean lower braking power, overloaded cars, higher than normal speed all rolled into one would make for one big wreck. * Reply: 4395 #: 4395 S1/General 28-May-89 04:21:55 Sb: #4383-San Berdoo Wreck--How? Fm: Robert I. Wright 74776,374 To: Dennis Larson 75555,705 (X) I know what you mean about automobile brakes. They really do go quickly if you strain them severely. I always pump my brakes on a downgrade and use lower gears. If I did not, I think there would be trouble. It seems the combination of factors really did them in. END
