Yeah, I know ......... Danes probably shouldn't buy Lego copies from China/Hong Kong. More than half of the trains shown are copies, some down to the last detail. (well, almost) There are some small but neat differences: The 629 "Frisco Fe" locomotive has opening doors. The 621 "High Speed Passenger Train" and it's 622 passenger car uses aeroplane windows. The 639 tracks and 640 switches are brown. (Rusty Rails on brown wooden railties) Most of the passenger cars can open doors AND the whole sides for access to minifigs. There are a few models that are quite unique: 623 Green diesel locomotive. 624 Green passenger car. (Looks fantastic with the Emerald Night) 625 Happy Christmas locomotive. 626 Happy christmas car. 627 Steam locomotive. 628 Red passenger car. 631 Heavy duty steam locomotive. The rest are more or less copies of Lego trains. Even though the pictures on the boxes show working lights, NONE of the models have real electric lights. All models are push-trains, but can easily be fitted With Lego train motors, and working electric lights. Train wheels tend to stick, and the trains are hard to pull, due to the the much higher resistance. Change the wheels to ORIGINAL lego train wheels. ENLIGHTEN WHEELS REALLY SUCK !! , and will wear you batteries out much faster, and may overload your train motors.
