The Home Office does not hold the requested data centrally. While the Home Office collects data on the number of hate crimes recorded by the police in London, we cannot tell from these data whether they took place on public transport or not. Furthermore, data are also collected from the British Transport Police but we cannot tell from these data whether the offence took place in London or elsewhere.
Recognising that hate crime is a serious and persistent issue, the Government is committed to developing a new hate crime action plan, working in partnership with communities to ensure we have strong measures to stop and respond to these deplorable crimes. In future, for the first time, the police will provide a breakdown in religion-based hate crime data to help forces build community trust, target their resources and enable the public to better hold them to account.
The most recently available figures for these police forces can be found in Hate Crimes, England and Wales, 2014/15, available here: https://www.gov.uk/government/statistics/hate-crime-england-and-wales-2014-to-2015
