DO TRAIN HAVE A "STEERING WHEEL" ?

HELLO FRIENDS,

  Most of time we are blaming loco pilot (train driver) for changing arrival & departure of  platform .
 but it is  totally a wrong assumption as loco pilot is not having  control of the direction of train (locomotive) . 

Now come to the solution of our question , "There is no steering in a train as all the steering is controlled & monitored by the control station .  The train wheels are fixed by solid axles, it is only direction controlled via controlling tower" .

Then what type of wheel is provided to loco pilot , Which is also shown in picture below

INTERIOR PICt OF  ENGINE DIVER CHAMBER

some parts of  electrical locomotive for better understanding........

• Electric overhead line 
• Panto-graph
• Auto-transformer 
• Rectifiers
•  Heat exchanges 
• Traction motor 
• Air/vacuum braking system

Auto-transformer with various tapping points

Note :- Generally tapping range b/w 0 to 32

In the Auto-transformer we required tapping to control output voltage & speed of the trains 

so above pic of wheel is "TAPPING WHEEL"  

loco pilot only control speed of the train , brakes & maintain stability on the fixed track as trains change there tracks by the liver mechanism .  

Trains wheel having tapper profile which are regularly finish by the CNC* ( computer  numerical control ). These tapper profile help in turning on the railway track.

*CNC : Computer Numerical Control (Computer + Numerical Control) 

• Numerical control is a programmable automation in which process is controlled by Numbers and symbols.

 • CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools .

 • Machining components with high Repeat ability and Precision  and many more advantage.......
