Genuine approved UK Health & Safety clothing - known as "train proof"! All the so called "photographers" have high visibility vests that allow them to ignore all rules.....
Some of the people involved in UK railway preservation consider that wearing an orange outfit gives tham the right to be obnoxious. I only wear the stuff when I absolutely have to - anyone wearing such outfits on locomotives should be shot. Okay I carry a HI-VI with me when driving but carrying out locomotive duties is excluded from the list of activities where such clothing IS required. There wearing of such a garish outfit should not absolve the wearer of responsibilty for their own actions.
