Train is regularly blocked on the circuit: it must be given a little push to restart but the worst is that I have problems with the lift mechanism from the first use by my little son 2 years. The crank is blocked and since the train no longer rises, the child loses interest! Also be aware that it is not possible to buy only so 1 train) on the day it is broken, we can get rid of all 2) impossible for two children to play with everyone on the rail a Circuit! I think V Tech should really consider selling "Roman" outside the circuit.
