When to switch on the number board light?
Posted by faraway on Monday, March 13, 2017 5:21 AM

Is it common practice to switch the number boards on and off together with the head and rear lights in this days?

Hi, Reinhard

My preference is to see the number boards lit all the time. Day or night. That's the way I remember them all through the 1960s and 1970s.

Modern practice may be different. I have noticed that many of the present-day prototype locomotives are using LED lighting for their auxiliary lights. Steps, walkway, engine room, ground lights, cab lights, etc. are LED.

Some newer locomotives have no provision for illuminated number boards on the end that is not normally facing forward. They are just painted or laminated vinyl engine numbers.

If in doubt, leave them on all the time. On some DCC engines I have, I wired the LED directly to track power so they are always illuminated. Some HO locomotives have no provision for illuminated number boards No Genesis and Bowser F units. 

Others may have additional input, this is just my preference.

Regards, Ed

Reinhard,In my experience just as soon as the engineer sits down and turn on the headlights and number boards.

The number board of the engine that is addressed in the orders or warrants is turned on, the headlight of the leading engine in the consist will be lit.

They may not be the same engine.

On the train Extra 1234 North or ABC 1234 North, the numberboards on the engine ABC 1234 will always be lit.  If there are three engines in the consist, north to south ABC1234-ABC6543-ABC7890, when the ABC1234 is leading, the headlight and numberboard on the ABC1234 will both be on.  When the ABC7890 is leading the numberboard on the ABC1234 will be lit and the headlight will be on the ABC7890.  If the train has a DPU engine, its headlight will be on low and the numberboards off.

In layman's terms  in a three unit consist as observed on NS and CSX  during after dark railfaning.

3345 is the lead unit then its number board and headlight is lit.

3360 number board and headlights off.I have notice some times the number board is lit.

3500 number board lit and headlight on low. I have notice the headlights off on the last unit and number board lit..

That's because someone didn't properly turn off the number board lights on the trailing engines.  As Dave said about the DPU, the number boards should be unlit.  Still, it isn't unusual to see a DPU with their boards lit up.  Some managers will take exception and give, what our company calls, a "coaching" event.  

Current practice where I work is to use the lead engine for train identification.  That is, if our track warrant for bulletins is addressed to a trailing unit, we call the dispatcher and have the address changed to the actual lead engine.  (An exception is for work trains and locals that change directions during their trip.)  We do this even though the rules would allow a trailing unit to be used for id purposes.

When a train is tied down and unattended, the headlight (depending on rules and conditions) may be either off or on dim.  The number boards would be left on.

Jeff is correct.  Having a "middle" unit with the number board lit was more common in train order days where the dispatcher might have train orders written to multiple trains referencing the a particular unit and so swapping unit numbers would involve a great deal of annulling and reissueing orders to multiple trains.  In the track warrant era it is MUCH simpler to change the engine number on the warrant (especially in CTC).

Seems there's a lot of variables at work..I've seen number boards on all three CSX or NS units or the trailing units number boards was off..

These are actual observations while railfaning after dark at Marion Union station,from by backyard(last year) and when I had a account with Railstream so,it's current and not dated information.

Railfaning is a wonderful thing..You get to see how things may not be has perfect as books lead you to believe.
