My suggestion is to add a laying position for seats (to use in sleeper cars). Basically, it will work like the SEAT_X, but there will be necessary to set position and direction (Ex: BED_1_-X or BED_1_Z [the "-" will define player's head position and the X or Z will define which axis the player is going to be laying along]

These "beds" are not going to work as normal beds, they will work as seats, meaning you would not be able to sleep since it would not make sense because of two main reasons:

• in #faq in the discord it's said that there won't be sleepable beds
• the traindriver would also need to sleep
