Pre-Metrolink, the frequency of trains from Oldham Mumps to M/c Victoria via Failsworth varied. In 1962, the off-peak frequency was every 20 minutes, with alternate trains from Rochdale/Royton. Later, after the Royton branch closed, it was every 30 minutes. In 2007, there were 4 tph, with a stopping service every 30 minutes from Shaw to Victoria, and a fast service every 30 minutes from Rochdale calling at all stations to Shaw and then Oldham Mumps only. Most services generally terminated at Victoria, although in latter years some services entering Victoria from the east have extended beyond Victoria for operational convenience.Oldham mumps had a 15 minute frequency throughout the day. Trains continued throughout the north of Manchester not just Victoria.
However, all of these frequencies are much lower than the current Metrolink frequency of every 6 minutes.
