Storm Emma: Snow disrupts transport across Wales

Gritting lorries were out in force on a usually busy M4 north of Cardiff

Public transport was brought to a standstill across much of Wales with a second day of disruption due to snow.

Most train services in south Wales were suspended and Cardiff Airport was forced to close.

A small number of vehicles, including lorries, have been abandoned along the M4 between junctions 26 and 32, the Welsh Government said.

Roads have been quieter than usual as many motorists heeded advice not to travel unless absolutely necessary.

RAIL

Only limited rail services are running, say Arriva Trains Wales and Great Western Railway

Arriva Trains Wales has cancelled all services in the south of the country until further notice.

Great Western Railway said it would be running a minimal service, adding: "It is a very real concern that, even if conditions mean we can move people in the morning, we may not be able to get them home later in the day, and on that basis we have to strongly advise customers not to travel on some of our routes."
