Someone said the light no flashing - I understand not every time but I mean on a street-crossing. There must be a warning signal!

BC Rail locomotives do/did not have flashing ditchlights. When approaching crossings, locomotives sound the bell and blow the standard warning signal (long-long-short-long). Busier crossings have automatic crossing signals.
