If youre a Norfolk Southern fan, these engines will get you pretty excited. Nicknamed the "Sonic Bonnet", (from the video game "Sonic the Hedgehog"), Norfolk Southern rebuilt these locomotives from former engines in their fleet and renumbered them 4000 & 4001, model AC44C6M, and applied this special paint scheme for their DC to AC rebuilds. These 2 wooden train engines #4000 & #4001 are sold as a set. The connectors will be set up just like you see in the pictures, one pulling and one pushing. We reversed the connectors on engine #4001 so you can play just like the real engines pulling their freight. These Norfolk Southern locomotives are the first wooden train of its design to hit the market. They even roll up and down wooden track hills. The quality of these wooden trains are of the highest standards. Fits all major brands of wooden track and trains. Made in the USA.
