We're looking at modding a 4 car group and using Smart Rise as the controllers. We've done plenty of simplex and Duplex cars using Smart Rise with no issues. Has anyone had issues with a multi-car group using Smart Rise's dispatcher. Thanks for any help on the subject.

I'd go with what works (mce). My company had never done a four car, but the three pack and even duplex is SLOW. I wouldn't want to turn over a group like that to a customer spending $200,000 +.
