The one downside to all this is that Bachmann On30 is getting expensive!
The upside of larger scale narrow gauge is less equipment is needed to depict a railroad operation in a given space.
The bigger problem is the drying up of locomotives from Bachmann, all that is left is the ill advised Tweetsie ten wheeler and the shunned but very good outside frame 4-4-0.
The OF 4-4-0 was probably one of Bachmann's better efforts and looks great as 55n3.
Just an odd duck prototype.
At least they are still making an analog Mogul available for under a $100.
Even the HO locos that could be converted to 55n3 narrow gauge have dried up in the world of RTR diesels.
Still cheaper than Sn3, On3 or HOn3.
Model railroading is a ridiculously expensive hobby in any genre.
