Correct! Intamin's Impulse coasters (Viper One's inspiration) use LIM technology to propel train forward and backward, LSM is slightly different and featured on the "Torque" coaster in game. Also, the sound should be quite different from the current sound we have in game for the Viper One.LIM sound effect: https://www.youtube.com/watch?v=T9p8x-D64vk LIM (instead of LSM) technology on VIper One track: https://www.youtube.com/watch?v=59Nvgl82iy4 To the average player, these "minor" details are definitely not noticeable. [big grin] Just recommending that a correct description for Viper One's technology be used since "LSM" verbiage is being used in the game.Am still grateful the devs are working hard on new additions/tweaks to the greatest sim game!
