Is there a large scale DCC decoder that can support 2 servos?
No DCC decoder will drive a servo, what for? Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
Not true Mel. Most of the European large scale ones, like ESU, support connecting a servo to a finction - they use it to have the valve linkage reverse when changing direction, or make the bell move when ringing, or stuff like that. Loksound v5 L and v5 XL both have servo connections, and CVs to set to make the servo do things liek change position on certain conditions and for setting the movement rate.

Thanks for the correction Randy, I didn’t know that. Very interesting. Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
Made me think of a model featured in MR back in I thinkt he 80's. It was O scale I think, the builder outfitted it with all sorts of extra motors and linkages. When changing direction, before it moved, the reverse link changed direction . The bell moved, I think the engineer pulled the whistle cord - the entire boiler wash chock full of motors and gears. I think the actual drive motor ended up in the tender - and this was a large Northern, in O scale. Well ahead of its time with animation. There are soem newer examples of HO locos where the fireman moves when the coal shoveling sound plays, or the brakeman stands on the caboose steps swinging a lantern. A very talented fellow in Australia makes those. Modern micro servos and motors make is possible in HO now. Plus more advanced electronics to drive it, while taking up less space. The Roco DCC crane was a marvel when it came out, now it's a DIY sort of thing - Geoff Bunza has done some amazing things with animating a wreck crane.
And more to the OP's point, it seems you have to look to Euro decoders like ESU and Zimo to get servo functions. Digitrax, TCS, and NCE offerings don't have servo connections. One place that carries a variety of these is Streamlined Backshop. Tony's has a decent selection as well.
Thanks so much Randy
