Ah. Yes, I did say that to Tony Koester when we were discussing operations in N scale. It seems that Tony had never actually seen an N scale layout built for operations that could rival a similar HO layout, until he saw the video of my layout that I posted on YouTube (I let him know that mine is only one of many similar high-quality N scale layouts out there, and not in any way close to the best one). But I told him that it takes more work in N. You can "get away" with stuff in HO (for example, less than perfect trackwork) that you can't get away with in N if you aspire to "zero derailment, perfectly smooth" operations. Most HO layouts I operate on do not use live frogs at the turnouts; in N, I think that is a recipe for operational disaster, though I know many N-scalers also do not power their frogs and swear they have no problems. Maybe - if you run modern six-axle diesels. But don't try that with finicky steam locos or an Atlas S-2 switcher.
Yeah, on operational issues in N scale, I have strong opinions. Not everyone would agree, which is fine. To each his/her own in this hobby. But I recall the comment of one of my model RR friends while operating on a very nice HO layout where he encountered some track problems: "They should have built this in N scale, like yours - then the cars would stay on the track".
