I'm not sure it's a typo but the DB BR 420 on HHR doesn't have LZB and from the last teaser it has LZB. I hope it's a typo.
Why is it even planned to be on HRR in the first place when the 420 that is being modelled is a refurbished Munich unit.
That is exactly my question. Why HHR, its a refurbished S-Bahn München unit with LZB. (S-Bahn München is the only S-Bahn with the DB BR 420 with LZB.)
