Two Small Trains / 小さな電車2種

I tried building a train using the single motor from LEGO Science. However, since it's very light, a single driving axle didn’t provide enough traction. So I raised the body by two plates and made a version with two driving axles as well. This motor is honestly so much fun to play with.

LEGOサイエンスのシングルモーターで電車を作ってみた。ただ重量が軽いため動輪一軸では牽引力が弱い。そこで2プレート分高くして動輪二軸の電車も作ってみた。ホントこのモーター楽しい。
