This Train really use 6 axles using Rodea_E9_wheel_layer_wheels_normal.kf with 6 controller , not like BB Train sp_8110_c44-9w have 6 axles but still using emd_gp38_2_wheel_layer_wheels_normal.kf, this controller only can use for 4 axles, that mean only 4 wheels or axles can be controlled by this KF. if you want to now how to the controller to work, open sp_8110_c44-9w.kfm in Nifscope then on the picture right click select Animation then select Attach.kf find emd_gp38_2_wheel_layer_wheels_normal.kf then look at wheels you can see only 4 wheels can be turn, please exit from Nifscope without save, then open again sp_8110_c44-9w.kfm for this time attach.kf find Rodea_E9_wheel_layer_wheels_normal.kf then look at wheels you can see 6 axles can be turn.
Happy enjoy it....
