Unfortunately I had no batteries at home therefore the technical part will follow.
The main differences to the old RC-locos are:
now 6 batteries type AA in the loco,
a new battery compartment which also can fully removed from the loco.
No chance to charge batteries in the loco, no plug available
Loco can be switched on and off
No need to change xtals when you have moren than one loco.
2.4 GHz remote control
Lights are changing in direction.
If loco stands still, 2 red lights on both sides.
If loco is running, 3 white lights in driving direction, 2 red lights on the other side.
A sound modul is implemented, two sounds available (engine noise and horn signal) both are triggered via remote control
