A beautiful loco that is fast enough and goes in both directions, without derailing too. Negative points: - It is not disengaged, unlike locos "powerful" red and black and can not be pushed by hand (well it is true that if you buy a battery model is not to push ... ) - With the character it does not pass under the bridges. - Difficult to stop with the switch system, we tend to move from one meaning to another without stopping.
