The first episode in a new series of Feedback, presented by Andrea Catherwood.

A recent edition of File on 4 Investigates went inside the migrant hotels at the centre of anti-immigration protests in England to talk to residents about their experiences. But listeners were divided in what they thought of the documentary. The journalist who made programme, Sue Mitchell, joins Andrea to answer your comments and questions.

While Feedback was off air we heard the news that veteran presenter Melvyn Bragg would be stepping down from presenting In Our Time after 27 years at the programme's helm. You've been suggesting your favourite names to take over - and we talk to radio critic Simon O'Hagan about the end of Melvyn's reign.

And Radio 3 took the time to celebrate 200 years of the birth of the modern railway recently. There was a day of specially scheduled programming - Train Tracks, in which listeners heard Petroc Trelawney travelling from Inverness to London by train in the company of other Radio 3 presenters, soundtracked by themed playlists. Petroc joins us to hear what listeners had to say about the celebration.
