first time going Birmingham and need get in city quick as possible, are trains regular to city centre and easy to get round airport to find the train?

Birmingham Airport Is Actually In Solihull , An Area East Of Birmingham However It Only Takes 10 Minutes By Train and 30 Minutes By Taxi

Trains take 10 - 15 minutes from Birmingham International to Birmingham New Street depending on intermediate stops; 9 trains per hour during the day; longest gap between two trains: 12 minutes

The train station can be reached by the Air-Rail Link, an automated people mover. The journey from the airport terminal to the railway station takes less than two minutes; trains depart every two minutes.

There is a really good rail link to the city centre from Birmingham International Airport - it takes about 10mins to get to New Street Station, within the airport there are signs to tell you how to get to the station and there is a monorail shuttle link to take you there

A long way from International airport to city centre, you follow the signs for the train station
