Woodbridge station has a sign up saying no bikes on Sunday and mac of 4 per carriage on Saturday so I wouldn't look to use as an alternative. However I think it has been "ignored" in the past
That's nice of Greater Anglia. Instead of making additional provisions, they reduce their existing ones especially.
FWIW I got a train back from Stowmarket, with a change at Ipswich on the Sunday afternoon and was totally fine. Didn't see any other Dun runners, in fact.
