On last evenings Demos with Dave, Dave demo'd the new Class A. This looks to be an exciting new engine from all new tooling.
He also mentioned with the new 4 digit addressing comes 2 way communication. The engine will provide the parameters back to the Base 3 Cab3 App to present a picture of the engine based on SKU# (internet connection need to pull from Lionel), real time fuel / water levels, name and road number without a sensor track!
I for one am really getting excited to see what else can be done with this. Dave showed some of the Cab3 app features as well but will do a dedicated Cab3 App show later. Looks like we'll have to wait until next year to get the Base 3 and App as Dave said he wants it to be delivered without issues.
