Pneumatics have the advantage over Hydraulics in that they are clean, require lower maintenance and respond quicker. When the application does not require that much force, pneumatics will do the job. Furthermore: the force needed for train doors should not be that large. It should only open and close the doors but not crush people that manage to get stuck in between

Each one has its advantages and disadvantages so it depends on what you wish to achieve.
With regard to compressibility how the working fluids in pneumatics and hydraulics differ?
Fluids are used in Hydraulics - fluids are essentially incompressible - they transmit forces well (e.g. a car bottle lack) Gases are used in pneumatics - gases are compressible - you can therefore store energy in a pneumatic system (e.g. a car tyre)
Why meter in and meter out is not in pneumatic system?
Meter in and meter out circuits are not in pneumatics as air is compressible.Hence uniform control of actuators are not possible
What are the electro pneumatics component?
Some actuator or devices are operated by compressed air. These devices are known as pneumatic components
What are the different types of electro pneumatics valve?
Electro pneumatic valves are mechanical valves but operated through pneumatic using suitable solenoid coils.
Should a machines tool-changing mechanism be pneumatically or hydraulically operated?
The tool-changing mechanism can be operated with air-pressure or hydraulic pressure. The choice depends on how the workshop lay-out is done. usually pneumatics are easier and cheaper to implement

Is operated an adverb?
No, it is not an adverb. It is a past tense and past participle. It can form participial phrases that are adjectives (e.g. the train operated by a freight company)
