Does Anyone Know How To Customize The Train Length On Ps5?

i wanted to customize the train length of the Baby Bullet Caltrain, i want to set it to 5 cars like how the real Baby Bullet is set instead of 6 cars

 

you can't just do that unfortunately. option one is formation designer which comes hopefully soon, option two is modding (however you are on console so uhh forget it) and option three is suggesting it as an official change, by doing it in the suggestions section here

 

Free roam, i've spawned on foot at Burgsinn once on KWG to make one intercity with 2 vectron at both ends of train, uncoupling the 101 loco, go a little foward, climb down and delete the loco for spawn the vectron, and add another one at back. This is the four option and the best for now
