2 Metro Trains routed to wrong direction

Postby davinp » Wed Aug 29, 2018 8:20 am

On Monday, Aug 27, A silver line train departed Rosslyn and got rerouted to the blue line

On Tuesday, Aug 28, A blue line train departed Rosslyn and got rerouted to the Orange/Silver line.

These incidents were caused a problem with the signal/switch. It would not have occurred if Metro was using Automatic Train Control

The first incident was entirely on the operator, both not having their train set to the correct route AND not noticing the wrong route when the left the station. The signals and switches were working just fine.

The second incident was a mistake by the ROCC folks who were manually controlling the with that day., that the operator failed to notice.

The main result is more training needed to make sure operators check their lineup.

It is nearly imposable to not notice what the lineup is. C route is a normal lunar, K route is a flashing lunar.

I've watched this happen in regular railroad towers, too. Not the end of the world. The signal indication should tell the engineer/motorman/operator what the route is set up for. So either they don't know how to read signals, or the signal system itself needs some changing.

Could it be that they're so used to automatic operation that they don't really look?

I don't know what signal aspects Metro signals display.

In 'real railroads' it is possible for the same signal indication to apply to more than a single diverging route. The 'Diverging' signal indication applies to any diverging route and at some locations there can be more than one.

They haven’t used full ATO for years, so I find that unlikely.

Wasn't the first run of the day usually without ATO back then?
