Almost 6000 ScotRail trains 'skipped stations in 2017'
Greens highlighted franchisee's failings as it reiterated calls for publicly-owned railways.
The Scottish Greens have highlighted "unacceptable" levels of stop skipping and overcrowding on trains as they renewed their call for a public-sector bid for the ScotRail franchise.
Almost 6000 trains skipped station stops last year while almost 470,000 seats on services were planned but not provided, according to figures provided by the Scottish Government.
Greens transport spokesman John Finnie said the "performance failures demonstrated the need for Scotland's railways to be taken into public hands as soon as possible".
A total of 5968 trains skipped stations in 2017 out of 765,458 services planned to run, equating to 0.78%.
The number of seats planned but not provided last year was 469,059 seats - 0.35% of the 133,371,277 seats planned to be provided.
Meanwhile, one in five train toilet audits failed in 2017.
Of the 3092 toilets audited, 686 recorded fails, accruing penalties of £225,870.
However, it was noted that "a significant number of fails were recorded for the maintenance record card being out of date as opposed to a fault with the actual facility".
ScotRail has appointed an industry expert to carry out a performance review and propose steps for improvement, including reducing stop skipping.
Mr Finnie said: "These unacceptable ScotRail performance stats demonstrate the need for greater investment in our railways.
"That investment doesn't come as a result of private operators running a franchise. It is vital that ScotRail is moved into the public sector as soon as possible.
"I welcome the cross-party approach taken by the transport minister in this regard so far but I would urge him to move faster, ensuring a public-sector bid is in place for the 2020 deadline."
A ScotRail Alliance spokesman said: "We understand customers' frustration when things go wrong and we do everything we can to provide a full service to our customers.
"We only miss stations as a last resort during disruption, to prevent knock-on delays to other services."

Transport minister Humza Yousaf added: "I have made clear skip-stopping should be minimised, particularly at peak periods, and acknowledge that this practice is currently recorded and reported as part of overall performance measures.
"While the figures referred to by John Finnie amount to less than 1% of overall services run, the ongoing Donavan review will look closely at performance, including skip-stopping.
"Once the findings of this are published, I will take the opportunity to look at the recommended steps for improvement and how this information is made publicly available.
"Only now, after repeated efforts, do we have powers to enable future contracts in Scotland to be let to the public sector and we are working to enable a public sector bid for Scotland's railways in the future."
