22K power sockets

wobbles · 30-05-2011, 20:30

Power sockets not working on 22306 on the 05.55 ex Gorey this morning.

29000 on 18.30 to Rosslare this evening.

I posted a query on Irish Rail's website and the answer explains what is going on.

"Our projects department discovered a problem with the individual trip
switches on the sockets and they have fitted a trip switch by carriage.
If a passenger plugs in a faulty device it will trip the carriage
instead of just that socket as a safety precaution. The driver can only
reset the system at the end of each journey."

So obviously, the drivers need to be briefed to go through the train and reset the breakers at the end of the journey.

Thats what we asked Irish Rail to do, but alas no response to indicate this is being done

This fault does not effect Dublin Cork Mk4 trains as they have proper individual sockets

I've done some investigation and it would appear that the socket trip switch (actually a current leakage trip) is rated at 30mA. Odds are the socket trip switch is not as fast as the coach circuit breaker so when a fault occurs the main trip switch is pulled faster than the socket one. So either the wrong type or rating

All other on train sockets on all other fleets are rated at 20mA trip current, where as the coach circuit breaker would be 30mA (standard home rating for an entire house)

For reference its the pesky trip switch on your home fuseboard, the big one with the reset button that kills all your sockets that is the problem on the train

Mark, perhaps if your home trip switch is pesky, it is you that is going round tripping the switches on all of the trains.

Power was working on at least 2 cars of the early Sligo Intercity this morning, but I think it was a different trainset. It was definitely given an exterior wash anyway - the train earlier in the week was absolutely filthy.

Its not me, haven't plugged in on an ICR in months, thats what 8 hour battery life will do to you.

I get the feeling someone is doing this deliberately as the scale of the problem appears to be significant

No available working plug to be found in the front carriage of 7.27 from Mullingar this morning either. Thought it had improved over the last few days but obviously there is still a problem. Has anyone contacted IR to see what the 'official line' is?
