Why are there BNSF locomotives at LA Union Station?

A couple of weeks ago I was surprised to see 5 BNSF locomotives on Track 15, at the east of LA Union Station.  We don't generally see these big boys in the passenger terminal unless they have provided a rescue to a long-distance Amtrak.

A little internet research reveals that Metrolink is leasing these at great expense to hook up in front of their new Rotem Cab cars.

So, bear with me.  The commuter rail (and Amtrak's Surfliner) run a push-pull configuration with the locomotive at one end, and a cab car at the other.  In one direction, the locomotive pulls the train as usual.  But in the other direction, the locomotive pushes with a cab car in front, running the loco indirectly.  Generally, the locomotives push the trains into LA and pull them out, for both Metrolink and Amtrak.  This means they don't have to try to turn the whole train around (which requires a wye of track, to allow a three point turn) or  move the locomotive from one end to the other.

Metrolink upgraded their cab cars a few years ago to a hardened form from the Rotem company that was supposed to be more crash-worthy, if they hit something.

But then there was a hideous crash in Oxnard, where some idiot got his truck stuck on the tracks, and an early Metrolink hit it.  The Railpac blog:
aAlmost 8 months after the Metrolink accident at Oxnard this year, the National Transportation Safety Board (NTSB) asked Metrolink to stop using the Rotem Cab Cars to operate trains in push mode. These cab cars can still be used in passenger service, but leased BNSF freight locomotives will be coupled to the cab cars and and used to operate the trains in what would have been push mode. So far the NTSB has not publicly given the reason for this decision. The most likely problem would be with the Pilot, which on locomotives and cab cars is the plow at the front which is used to push away debris off the tracks to prevent derailments. It appears that a major problem during the February 24th crash in Oxnard may have been from debris from the crash with a large pickup truck and trailer on the tracks. It is likely that debris got under the wheels of the leading Cab Car at speed causing the Cab Car to derail. This resulted in the Cab Car going out of control, uncoupling from the rest of the train, spinning 180 degrees and rolling over on its side.
What is the Pilot, or plow, you ask?  It's the little strip of curved metal you can see just above the tracks in this picture I took last week, a modern-day cow-catcher that is supposed to prevent the car from riding up over debris and derailing. Apparently,  it failed in the Oxnard crash. IF you were to look behind it, you would see that it appears suspended on vertical posts.

For comparison, here's what the rather heftier plow on the cab car of a Pacific Surfliner looks like. From the back, you can see a heavy bar across the bottom of it, and big braces  going up at a 45° angle.  College physics was a while back but this seems like a more substantial structure.  

And here's what a plow looks like on an F59 Surfliner locomotive. 

SO Metrolink is leasing at great expense super heavy locomotives essentially to protect the cab car from structural failure. 

In block letters, Metrolink should emblazon each BNSF locomotive with the words, "BNSF MEANS TONNAGE".
No kidding, those things are HUGE. In another blog,  McGillis notes the engineering and environmental complications and safety implications of  adding these locomotives, suggesting a cabbage car might be more effective. 

Thing is, I haven't seen any Metrolink trains going in or out of LA Union Station with one of those big orange guys in front of the cab car.

Or as we commuters call it, the Death Cab. I never sit in the cab car  if it's leading the train.

The problem in all of this is the number of at-grade crossings where trains and cars share an intersection.  There are many of these throughout the LOSSAN corridor, with many stupid people (and a few suicidal ones) making collisions  inevitable.

And meanwhile, the Rotem cabcars apparently aren't what they were hyped to be.

Can Google help prevent accidents at grade crossings?

After a sharp increase in the number of rail crossing accidents last year, the Federal Railroad Administration plans to announce a new partnership with Google on Monday to provide the locations of all grade crossings in the company’s popular map application.

Google has agreed to include information from the United States Department of Transportation’s vast database to pinpoint every rail crossing in the country in Google Maps. Google will also add audio and visual alerts to the app for when drivers use the turn-by-turn navigation feature.
Yes, please.  Anything to help.  And meanwhile, respect the train!

Yes, we're still here

YEs, we're still taking the train every day on the Power Commute to Irvine or Los Angeles.  Much of our conversation and photo-taking has moved over to Twitter. Call it the curse of the smart phone.

It's been a bad week for Amtrak this week, with three fatalities in the LOSSAN corridor.  (2 in one day, on Wednesday).  We don't know the situation with all of them, although apparently one of the ones on Wednesday was a guy wearing headphones and filming near the tracks.

That one cleared in a couple of hours, but the 2nd one, near San Clemente,  took nearly 5 hours to clear.  Lots of trains were canceled and there were rolling delays.  Although Metrolink ran a bus bridge between Laguna and Oceanside, that doesn't help us Amtrak commuters;  cab fare from Oceanside to Solana Beach is around $50.  So it was time to get a Stone beer from the bar and read the news on line.

And our poor Amtrak crews-- what a brutal week for them.  Regular commuters know our conductors and LSAs and some people even get to know the engineers.  Trespassing incidents are tough on our crews.

People:  if you see tracks, there are trains.  They are big, they are fast, and they are surprisingly quiet.

Just respect the rail.
