TfL’s abolition of the Hammersmith & City line.
They’ve merged it with the Circle line - which easily could have been described by opponents as ‘abolishing a tube line’ – which was in fact why it hadn’t been done for decades when it had been considered.
TfL’s confident framing of the debate has meant that almost all the focus has been on the positives.
