So where does the 1:150 1/150 scale come into this?
Well that scale lies somewhere between the two, more so towards the 1:148 size. But for this you will have to let your imagination run wild! For this demonstration I have shown on here represents the two largest differences of all three scales.
Lets repeat the test on a road layout, with background scenery and potential buildings.
The model at the front is the larger of the two models.
again only about 20mm separates the two, but its almost impossible to tell the difference.
Right next to each other the difference is again more obvious.
But with most N-Gauge N-Scale railway layouts for that matter. Nothing is lined up symmetrically unless its a model of a car sales forecourt full of different scale models of the same design. (An unlikely scenario) As you wouldn't order two of the same models in two different scales?
Having a car in scale 1:148 next to a completely differnt model such as a flatbed truck in scale 1:160, would be nearly impossible to tell they are of two different scales.
(The most likely scenario).
To finish, here I have placed the models together without any distractions.
So the question, 1/148 vs 1/160? does it really matter?
Well every person has there own preference, but personally after doing this testing for myself. I think it makes zero difference to the effectiveness of your railway layouts.
