THAT choice is up to you.
I have done both.
It depends: are you older and eyes not so good? how about manual dexterity? how about mobility period? If so, maybe HO is for you. OR will it be happening sooner than you think?
Of none of that applies…maybe N scale, but .HO is a great place to start. and 12x11 will give you quite a good sized layout in HO.
HO:
~most popular, easy access to many different scale model thing/kits/locos/RR cars/structures/people/autos.
~ cheaper than N as the popularity means more profit at lower prices.
~many magazine articles are geared towards HO
~ All hobby shops will carry lots of HO stuff
~ larger than N and easier to work with/on
Higher detailing easier to do
N scale:
~ smaller than HO, gets more into the same space
~ is about 1/2 the size of HO so almost all plans for building structures/cars can be reduced
~ will make a VERY NICE {large} layout in 12 x 11.
~are still many major road names available in N scale…
~ some items about he same cost as in HO
~ less detail, BUT still good details available…
BOTH:
Have option of DCC operations {controls the loco, NOT track current to control a loco’s movements adn actions}
Have many major liveries to choose from
Have popular track plans listed to use
Both are considered great scales
So- now with some advice, the choice is up to you.
I suggest you do some research FIRST, then decide. DO research to find out what livery{ies} you want to model, what is available in those liveries in each scale, study various scale track plans to see what you like, decide what kind of layout you want {operations, large yard, mountainous, countryside, city, etc}, then decide how that will fit in your space, your abilities to see. operate, get the things on the track, keep ehtm on the track, and THEN decide which scale you want.
