*** Hi all.

I'm a long way from any 170's/Turbostars to check personally, so.... could someone please tell me:

What is the item the arrow is pointing to in this picture?

Also, on other turbostars I've looked at I see several similar shaped items each side of the door at the same height - what are they?

Many thanks.

Looks like the door interlock light as fitted to all sliding door stock since time immemorial. It lights up orange when a door is open on that coach. If the guard tries to close the doors and can't get the interlock circuit to say they are all closed then this is a way for train/platform staff to find the problem more quickly.

It is always in the centre of the bodyside. I'm not aware of anything similar close to the doors, can you post a photo of this feature as I think it must be something else.

They are 'Hazard Lights', they do show when the doors are open. On 319s (I can't really speak for 170s) they also allow drivers to see where certain 'faults' on the unit are.

Every passenger door on a Mk2/3/4 vehicle has a similar light (meaning there are normally two on each side), but only the Mk4s were built with them.

Hi Richard,

I dont have a lot of knowledge about modern stock but have found two images ...... the first showing as you say at the same height the items on door level look like some kind of venting.
In the second picture the light.

Hope this helps

They are the door open warning lights, but I'd not describe them being fitted since "...time immemorial" as they were never used on main line slam door stock.

London Transport and its predecessor companies have used sliding door stock since the early 1900s but without external door open warning lights. They only started using the warning lights in 1949 with the District line R49 stock. London Transport never fitted door warning lights to their slam door T stock.

***Thank you all most sincerely - a quick and detailed response in no time at all! (and thanks for the added images Nick)

For those that were wondering why I wanted to know, I asked the question as we like to make lighting as complete as possible when we can do it, so confirming that detail will make it possible to be just a little more accurate than before!

Being a pre WW2 period modeller I was interested to hear they were also on post war coaches, as I'm also now g3etting involved in a late steam/early diesel layout so will need to become more "up to date" in the smaller details for my own modelling too!!

Can I presume from their purpose that they were/are always Amber/Orange?

kind regards

Richard

Cheers Edwin.

Nicks photos show the other items in line with the centre lights clearly - they are indeed vents as was surmised. On the models I've seen them on they have either been merely painted (n) or in OO not very well defined, so it wasn't clear at all to me until I saw Nicks very well defined images.

kind regards

Always orange as far as I'm aware. There's probably a standard somewhere that forbids other colours due to potential confusion with signal lights.

If you want a real challenge, the door buttons light up in yellow when doors are released...

***Hmmm. Are they the small yellow bits on the door in Nicks photo? Its doable in 4mm scale! N will be a challenge though, my smallest drills are 0.3mm!

any volunteers to photograph them close up?

If I can get a good detail photo of them, why not - I will have a go at it!! Any takers on MRF for the photo?

Hi Richard

Just curious what do you use to drill with a 0.3mm bit , I have seen some PCB drill bits on 3mm shafts designed to fit in Dremmel style tools but they are always a bit pricey . Are there small chucks available to fit a Dremmel?

Regards Zmil

***Yes, there are chucks for the Dremel that will hold 0.3 - Your local Bunnings (should) have them at about $20~25. I sue them ina pin vice for plastic though - a Dremel is way too fast!

The button is the same as the round yellow one shown on the 156 (156s themselves may have different buttons depending on when and how they were refurbished). You can just see it between the two windows on the door itself. A ring of yellow LEDs lights up between the central silver button and the outer yellow ring.

The yellow triangular thing is a sign warning of the danger of entering the train when the doors are closing.

I think you'll struggle with the Farish N gauge Turbostar - one coach is entirely filled by the chassis!

*** Yes, I know the Farish Turbostar...

If I can manage fully working Stevensons link valve gear between OO scale loco frames a little thing like a solid chassis block is no problem... A Drill press, a Dremel and a milling cutter used carefully can do wonders.

Whether I'd bother in N scale is another thing though!

I think there are two styles of Hazard/Warning light. The older BR stock has the orange square type, the newer type is made out of LEDs and has found its way onto older stock but is on most post-BR built stock. This web page shows both types, although it is based on the class 156 units rather than the 170

As far as I know only one UK train type has Warning/Hazard lights that are not orange, and they have a special rule in the rulebook, although I can't remember exactly which module it is in, and it goes something like:

"If you see blue Hazard lights displayed on a train, ignore them."

The train in Question? - Royal Mail's Class 325 EMU.

I don't know the purpose of the blue lights.

(P.S. Nothing on the railway is ever amber! It is either yellow (Signals) or Orange (Hazard/Warning lights)
)
