GordonC Posted March 16, 2018 Share Posted March 16, 2018 The normal headlight position when it was fitted on Class 47s always looked to be slightly offset towards the drivers side, but looking at photos of Class 86s it always seemed to be centred. Was there a reason for differing positions of where the headlights were located when they were fitted during the 1980s? Link to comment Share on other sites More sharing options...
royaloak Posted March 16, 2018 Share Posted March 16, 2018 Possibly access behind the panel. 1 Link to comment Share on other sites More sharing options...
RMweb Premium Davexoc Posted March 16, 2018 RMweb Premium Share Posted March 16, 2018 IIRC there were standing orders as to placement of headlights for each class. I guess it was partly down to aim of the beam, and partly down to what was physically behind the unit. Looking at the 86s they are usually between the push/pull jumpers centrally, although 86260 is strangely offset to the secondman's side. I always thought they were pointed slightly left so as to aim towards any lineside signage. Dave Link to comment Share on other sites More sharing options...

Dave Things like the curvature of the front end were taken into account in the position of headlights, as there was on the first types of headlight fixtures very limited adjustment on the fittings, unlike the later ones.

deltic79 Posted March 17, 2018 Share Posted March 17, 2018 On a related note, does anyone know why the headlight position on the class 31s varied between lower centre and offset to the right above the footstep? Was it perhaps simply different works carrying out the additions? Or a change that occurred over time? Link to comment Share on other sites More sharing options...

Was it perhaps simply different works carrying out the additions? Or a change that occurred over time? The headlights on 31s first started to appear with the HGRs from Doncaster, this used the original style of headlamp mount that had very limited beam adjustment so was placed at the drivers side.When it was fitted on the former communicating door panel it was the later style of mount that had more adjustment (these mods were usually done at depot level).

cheesysmith Posted March 18, 2018 Share Posted March 18, 2018 A related class 31 headlight question. I'm aiming for a 80s layout, and the peds are required. What dates do these headlights start from? Looking at photos, there is a few rail freight machines with the offset headlight, but very few, if any, red stripe rail freight fitted ones. And when did the centre mounted headlight start being fitted? Looking at the photos, the 31/4 didn't appear to be fitted until the late 80s? And we're any non HGR machines fitted with them?

RMweb Gold rodent279 Posted June 27, 2018 RMweb Gold Share Posted June 27, 2018 (edited) There's a similar thread to this that I can't find now, on class 86 headlight positions.Prior to the universal introduction of the sealed beam units that we all know & love, several class 86's had one mounted offset to the drivers side, next to the tail light.Which ones were they?I can think of at least:-86010/016/027/030/03886101/10386214(For the sake of clarity, I have listed 86/3's & 4's using their 86/0 numbers, as I believe they all carried the headlights before conversion. I think all the offset headlights were removed prior to conversion to 86/4.)Can anyone confirm, and/or add to the list?cheers NBelow, photo of 86038 at Euston, the headlight is just visible. 86316 passing through Milton Keynes. 86101 stabled at Euston.
