Having a mixture of N,HO and HOm I'd vote for HOm. Why?
In the prototype trains tend to be
- short length (3-5 coaches),
- curves can be vary tight (radius as low as 45m on RhB), this translates to 51cm in 1:87.
- inclines steep (7% - 1:20)
which therefore look more realistic on the model. The scale is 1:87 so you can still see a lot of detail compared to N where things are tiny. There is also a good selection of high quality models from Bemo with many beautiful custom liveries.
Whats the opinion?
