For me, the answer is Yes.
This could apply to all modern operating systems, including TMCC, Legacy and LionChief Plus, as well as DCS, in which the transformer voltage is set at 17 or 18, and trains run slow and smooth using a handheld remote or smartphone. Here, I'm focusing on DCS because that's the speed control modern operating system I have, and because I think our beloved moderators would like that.
With my sharp 031 curves and heavy Postwar operating cars with sliding shoes that can get snagged on the 022 switches, DCS has been a very positive game changer, almost entirely eliminating derailments. That, in turn, means greatly reducing the occurrence of circuit boards getting fried during derailments.
What do you think? Do you have much fewer derailments using DCS or other modern operating system with speed control, compared to the derailments you had running conventionally?
