One Worker, Wrong Part—LIRR Outage

Not sure if it is fair to blame one worker for the disaster on September 29th

Only explanation is that more oversight (whatever that means) is needed ....

Nice story. The problem with is that not a shred of the story is true.

What's the real story? Thanks.

sounds like upper management dropped the ball and theyre looking for a scapegoat through the media...

This might be a "supplier" screw-up as well,by not having the required parts on hand,along with an"outdated" circut diagram in the shed.
Is this the same company thats suppling the control setup for ESA??

L I Tool,

Lots of inquiring minds would like to hear the real story if possible. We dont want to get you into any trouble so if its not possibe its understandable.

The equipment, as designed and furnished is simply not resistant to the surges experienced with lightning hits.

This is common knowledge within the Company and its acquisition and faulty design was warned against by the experienced field personnel. The equipment will fail when struck by lightning next time.

It will continue to fail until technology advances to the point where electronics can be specified that are as reliable as the stuff it replaced that was built in 1910.

Is LIRR only purchaser of this system or do other railroads use it ??

Others use somewhat similar systems from the same manufacturer. They don't work in the rain either.

How does one protect against 100,000,000 volts that just traveled 10 miles to strike the right spot.

you got any examples other than LIRR ?

You protect against lightning by avoiding solid state equipment or isolating it from the electro-mechanical stuff. That's how other roads and the military do it.

lets just say that about 80% of all modern railroads use nothing else than solid state equipment.
and Ansaldo Breda is not a new kid on the block, MNCR has solid state equipment and gets lighting too.
so does the Shoreline to Boston.
So who has problems in rain Tool ?

for info Ansaldo STS USA (formerly Union Switch & Signal)
