We have this locomotive for over 3 months.
This engine has endless power, we let them go 6 cars, no problem, not even in slopes. For more supporters of the magnet no longer holds and cars dissolve ........ makes the game fun but not detract.
The locomotive has two engines, here is the benefit (much force), however the curse, because these are (can be a toy is not supposed to) out of sync.
Especially with gradients so the first two axes stand out a bit and here it can quickly lead to derailments. We have solved the Prblem By placing another -not electric locomotive.
The battery lasts -bisher- always at least one Round and since we have a second geldaden we do not need to wait.
A disadvantage is in my opinion the fact that the engine does not start / stop function and therefore does not stop at the bus stops.
Otherwise, (we are talking about toys!) I can only recommend this locomotive.
