Online top up is back online

Clonsilla station last night.
Tried to Tag off with smart card reader on pole on Maynooth platform after arriving from city centre. Tag machine displayed 'Ready' but gave error each time went to tag off.
Went to other platform and tagged off succesfully. Maybe card reader Maynooth platform is faulty.
Same smart card worked correctly at turnstile at Connolly and Tara.

That one has given trouble before. It will be looked into by Irish Rail, they follow this thread.
