RAIL passengers are set for three weekends of disruption between Huddersfield and Sheffield.
Engineering closures on the Penistone Line later this month mean trains will run from Penistone to Sheffield only.
The works will last all day on Saturdays and Sundays 12-13, 19-20 and 26-27 September.
A bus service will be offered between Huddersfield and Penistone, calling at intermediate stations and leaving earlier than the advertised rail service.
Huddersfield to Sheffield journey times, normally about 1 hour 22 minutes by train, will be extended by about one hour.
Passenger transport chiefs have already announced bus replacement services for travel between Huddersfield and Manchester on Saturdays and Sundays in September.
Train users are urged to check their weekend travel arrangements with National Rail or rail operators.
