use 1 and 2 to switch between models. the train from HELL has a lot of health use space to fire cannons on both models w is for machine gun on train from HELL a is for mouth clanking on train from HELL ( dont ask why guys, plz.) s is for the flamethrower, but you need to press I and s at the same time for it to ignite. ( it will take some time.) d is for laser eyes. model 1 is more simple don't mind the sound effects. the drum machine is for the noise when both models run on the infinite rails. if you see clank a lot of times, don't mind that, its just a STUPID CLANKER!!!!!!! for the even bigger technodemon, it takes time for the health to go down. idk why.
