The train will not move up a slight incline with any passengers. Instruction manual says it will go 6km/h but it does not exceed 4 at any time. No response from any support, and when I reach anyone they try to sell me another train instead of helping resolving my issue.

awesome product, excellent quality and exactly as described. the communication from the seller regarding the delivery was perfect. I received this item within the delivery time expected. Will definitely recommend this seller to everyone interested in this product.
