Millions will be spent upgrading the Upfield train line, but Melbourne's most sluggish peak-hour service may not improve for another seven years, when the Metro Tunnel is built.
Transport reporter Timna Jacks says major upgrades promised for the line will not boost the frequency of peak-hour services.
Upfield line commuters want to know why Labor won't duplicate a single section of the rail track that is causing bottlenecks on the line, as it removes the level crossings. Fair question.
