street lamp placing

Postby 4472 » Wed Jan 17, 2018 4:49 pm

Going to install some street lamps on the layout. Is there a scale distance to follow or should I just go by eye

According to the Highway Code, it is generally recognised that a ‘system’ of street lighting could be three or more lamps spaced not more than 183 metres (600 ft) apart. So on a 00 layout it will be 2.4 metres, but that would not scale very well especially on a small layout, So use the "not more than" to decide yourself what looks right.

Wherever you put them try to get them so that they don't cast "shadows on the sky" it really shouts "backscene"

Go outside and have a look at just how much light sreetlamps throw - it's not very much! Model streetlamps that you can read by screem "trainset". A gentle glow is enough...

I made my street lights the same as the idea on "web site articles" on here, posted a couple of years ago, Pop rivets, brass tube, plastic spoon handles and grain of wheat bulbs, but they were placed so they looked right in front of a row of houses and shops. I am happy with them so that is all that matters, it's your railway build it how you want it.

Hi 4472,

I believe they are spaced based on the speed limit. So, thirty yards for a thirty limit and forty for a forty.

If there are street lamps no more than 200 yards (minor variation allowed) appart a road is deemed to be restricted to 30mph unless there are signs stating otherwise. The lights don't have to be lit for the rule to apply, but they do have to be mostly visible. One speed camera partnership lost on appeal as the lights were mounted on wooden electricity poles, which were largely hidden in a hedge and the lights had switched off at midnight. There's no requirement for the lights to be spaced according to the speed limit or size of road, here might be recommendations but it's down to the local authority how well lit a road may be.

Everyone is quoting rules 'n' regulations, but essentially they are both a modern invention and to set a maximum distance.
In reality, the spacing is determined by two factors, how much light each lamp gives out (bulb light output/height/spread angle) and the desired lux on the floor. They were first fitted as gas lamps (very poor light output) so were very close and later converted to electric (so spacing did not change). Later electric bulbs were not much better and even when sodium and mercury came out that light output went up and height and therefore, distances between new lamposts could be increased. An example is my road that still has cast iron fancy posts that are about 8-10 houses apart.
