PTC -- Epic Fail ?

Postby Commuter X » Tue Apr 24, 2018 4:17 pm

According to Newsday -- "The $1 billion system’s inability to do precisely what it’s supposed to — automatically bring to a halt a train that violates a stop signal — has raised new concerns about the program for MTA officials, who learned about the test failures during a Monday meeting of the agency’s railroad committee."

"Metro-North president Catherine Rinaldi said Monday she remains confident the MTA will achieve that goal.

“We fully expect to be compliant with the federal requirements by the end of the year. That has not wavered,” Rinaldi said. “It is our highest priority, and we’re killing ourselves to get it done.”"

God what a choice of words....

Epic fail? Hardly. Its a new technology being overlaid an existing signal & control system. The likely had similar pains when ASC was implemented in the 50's

Both MN and LIRR are installing the same system,most of MN's signal systems have been updated to almost new and module components,
a good part of LIRR signals date back to PRR type signal systems with Relays,and old style electronics,mixed with newer upgraded gear in
some sections of the RR.
ACSES II is an overlay system that works with the signals,may have integration problems with the old PRR signal systems.
Harold is a nightmare with a mix of old and new signal systems,and is not yet in it's final configuration.

the transponders for ACSES may not initially be set at correct locations, but that is what testing is for .

Typical Newsday reporting. Exaggerates the issue and quotes things out of context. As someone else just said above: it's a new technology and there are glitches that will take time to work out. But of course Newsday never lets the simple facts get in the way of a sensational story.

They're not the only ones. CBS News made it sound like there are no safety precautions in place at all.

Yes, they might have thought to mention LIRR's automatic speed control system, arguably an early version of something like PTC that LIRR began installing in the 1950's after they had two very serious train collisions.

The news media as a whole,has the BAD habit of editing out parts of a story to fit the "slot" of time on the evening news,so any mention of
any "active safety systems" gets cut for the NTSB PTC sound bite at the story's end. :(
