@Norton posted:With just the ZW you can get whistle or bell depending on wiring to the track. Reverse the wires and you will get the other sound. To get both whistle and bell you need a bell control to produce the opposite DC shift to the track. Sounds you won't get without a TMCC controller are crew talk and tower com. You don't need a battery for conventional railsounds. The battery just maintains sounds for brief power outages when running in command mode.

Even with a TMCC controller, you are not getting Crew Talk and Towercom with this engine. 
Note on Page 9, the 2 and 7 buttons on the keypad are called out as "reserved for future use". Lionel acknowledged something was on it's way, but these were not included features yet.
I'm surprised the normal cautions about adding TVS diodes, using a faster breaker than the internal one on the PW ZW, etc. have not come up. While not a more modern Legacy engine, these still qualify as potentially at risk when in use with a "bare" PW ZW.
As for the YLB, while I'm sure it's an excellent product (I don't think John makes any that are not excellent products! ), you might want to just try the engine with and without a traditional battery first to see if the interruptions during direction switching bother you that much before you go to the expense and trouble to install one of those. (Unless you already know those interruptions will bother you, then go for it ASAP )
