CUSTOMER satisfaction with myki on trams, trains and buses is decreasing since the $1.5 billion smartcard became Melbournes only public transport ticket.

Public Transport Victoria figures released today show bus customers are significantly less satisfied with myki compared to the same time last year, with the approval rating falling from 71.6 to 61.5.

While overall satisfaction with Yarra Trams remained steady, myki satisfaction is falling.

PTV’s Track Record report revealed myki’s approval rating on trams fell from 61.3 in the December quarter to 57.2 in the March quarter.

Customer satisfaction with myki on trains also decreased from 63.2 to 59.1.

The troubled smart card replaced Metcard on December 29 last year.

PTV spokeswoman Donna Watson said satisfaction with the delivery of service, the primary driver of overall satisfaction for train, remained statistically unchanged.

``As we've become a myki only system we've progressively made improvements that customers have told us they want including the introduction of card sales and top up on bus, on the spot replacement and changes to auto top up,’’ Ms Watson said.

The State Government axed plans to allow commuters to buy and top up mykis on trams after receiving a secret Deloitte report into the overtime, overbudget system.

Customer satisfaction with train operator Metro is also on the slide, falling for the third quarter in a row.

``There was a notable decrease in satisfaction on the metropolitan train network with `overall price’ (down to 60.4 from 63.2 in the December quarter),’’ Track Record said.

Metro received an $840,000 bonus for meetings its performance targets.

Overall satisfaction with the public transport network declined from 63 in the previous quarter to 61.7 in the March quarter.
