The reality is thats really all you need for Command Control. My 990 was getting repaired so was using my Cab1 and base. Start your engine, run it, ring the bell, blow the whistle, start/stop smoke, open couplers, create lash ups. It will initiate whistle smoke and swinging bell. What more of value does a 990 do for you. 99% of the time I pick up my Cab1 even when I have my Cab2.

Well, I join the fray . I find the Cab II a pleasure to use, and aside from sending it back to Lionel when first purchased, I haven't touched my old Cab 1 in over ten years - though it does stand-by as a dutiful soldier in these strange toy train/economic times. Aside from the quilling whistle and train brake levers, the digital readout screen is a welcome improvement over the Cab I. My only complaint is that Lionel couldn't get around MTH's patent on scale MPH, but the Cab II does indicate both speed increments and specific engine addressed.
I think Lionel has made a mistake in banking heavily on apps and Smart devices, though I understand economic considerations of their plan going forward. Their decision has put me off on pre-ordering any new Legacy engines, and that custom run PRR Class A from Muffins was calling my name. Just as well because I don't know how I am going to pay for the PE Acela set . Swipe technology has its fans and place in this virtual world, but there's a neat and happy medium between analog and digital. Analog buttons, dials, and levers are just plain neat. Heck, if I had the brains I'd add a lever throttle to my Cab II - then it'd be perfect, though probably a bit bulky Of course, I still drive a manual trans Mustang GT - and wouldn't trade or sell it for any of these new fangled automatic super computer-controlled cars out today.
For us old-timers, there is comfort in that Lionel is continuing the Cab 1L. Nonetheless, I've been scrambling to find a dealer with 993 sets still left in stock, just to have a backup...it's amazing how many train shops don't have websites...means lots of phone calls...kind of nice though, chatting with some of these guys and getting their take on the hobby and how it's evolving, or regressing, depending.
