We caught up with Cllr Robert Rigby outside Marylebone Station.
Hello, my name is Councillor Robert Rigby, and I'm standing outside Marylebone station.
We here in Westminster are desperately trying to become carbon neutral.
We're working with residents and the Government to ensure that the trains that come into and out of Marylebone station are no longer diesel, but a more friendly hybrid version.
As I say, working with residents, working with Government to make sure that we achieve that and it becomes a less polluting, more environmentally friendly station.
Thank you.

Local MP Nickie Aiken launched a parliamentary petition on this, which was presented to 10 Downing Street. Read more on her website.
