Warning Signs For Model Railways?

7 posts in this topic

A while ago now, some "exhibition layouts" had a more fun way of saying "Do Not Touch".

 
Like the Southern Railway "Do Not Touch Conductor Rails" notices...

 

Danger!

Do Not Touch Conductor Rails

12,000 mVolts
 

(This was before Zero 1 and the DCC revolution!)

 
Also...
 

Atchung!

Ninen Fingerpoken!


Now older Transformers had a loud "Hum", quite noticable.

Modern "Plug-top" (Switch Mode?) Transformers are much quiter... so it can be hard to tell if they are working!

That hum is the 50 cycles a second frequency of the 240 Volts AC mains...

(Or 50 Hertz, not the car rental co, the measurement unit! ;) )


You get the same sound from a National Grid Substation, still 50 Hertz, but a few thousand volts (Or KV, Kilovolts!).

 

Current (!) BR Overhead power lines are energised at  25KV...25 thousand volts.


Most Model Railways are energised at 12,000 mV (millivolts) DC Control,  or around 15,000 mV (DCC).

 

That is 12Volts DC, and around 15 Volts DCC! :D

Nice tramway sign!

 

From further investigation, it seems that DCC line voltage is actually 18,000 mVolts AC...

 

or 18 Volts AC....according to a PECO Shows-You-How booklet...

 

I am just starting on the DCC road.... ;) (;

How about this one for model tramways?

It is an actual sign from Melbourne, Australia.

 

So when are you putting a small one on terminus all change for the plastic people and a reasonable sized on on the layout for the big people who should know better.

Hi alI

I did see a sign once that said look with the eyes, not the hands.

The Late Jim Varney of Varney Models fame in the 1970s and 80s had two lovely warnings but these days would be considered non PC:

Children - Don't touch my models and I won't touch your mothers!!

or

I have a filthy cold, touch my models and I will breathe on you!

As an aside, I arrived back into Southampton with a shipboard virus which is now 24 hours flu and I still feel like c**p!!!!

"Free range children will be given a double caffeinated coffee with six sugars." A warning to parents rather than their little darlings.
