Rail commuters across Britain suffered cancelations and delays on Monday, the first weekday of a new “improved” winter timetable that went into force early on Sunday.

Staff shortages, signaling problems, a landslip and ongoing industrial action were among the issues affecting services on Monday morning, local media reported.

Some early morning trains operated by Northern Rail were also cancelled on Monday due to a shortage of drivers.

As of 0800 GMT on Monday, the TransPennine Express had 24 cancelations listed for the day due to a shortage of crew or train faults.

Some 52 percent of South Western Railway (SWR) services failed to arrive at their destination within five minutes of the advertised time by 0900 GMT.

Due to strike action by the National Union of Rail, Maritime and Transport Workers, travelers on SWR have been warned of fewer trains, earlier finishes and some replacement buses throughout December.

Services are expected to be affected every day until Jan. 2.

Passengers on Great Western Railway were being warned to expect cancelations, delays and fewer trains between Reading and London Paddington due to a fault with the signaling system at Maidenhead.
