Filed a report through the TTC customer service form with both reader IDs (BY-03 and BY-04). Got an auto-reply with a ticket number. Also taped a paper 'out of order' sign on each one this morning and the queue split evenly.
Two of the four PRESTO readers at the Bloor entrance have been showing an error screen for three weeks. Morning rush backs up to the stairs.
Put a printed 'out of order' sign on the dead readers so people stop queuing behind them, and report them through the TTC customer service form with the reader IDs.
Someone who knows who at the TTC actually handles reader maintenance
