If you doubt Railway 'people' it is understandable, but if you doubt 'railway computers' it is surprise and not digestable.
First know well that, any information about status of a seat on a particualr train on any particular day must be centrally monitored by single station servers, and not separately.
and on showing the status, on Eastern babu nor western nor northern nor southern babus play the mischief.
If...
more... you think, they can play mischief, then they also can swindle the entire Railway money too, but it can not be done so easily.
If you think that Eastern Rly computers showed WL, and you bought Tatkal, and on day of travel , train was vacant, it might be possible that certain boggy passengers migh not have arrived for travell, or might have cancelled en-masse due to geo-political situation in that particular area.
Even in Western countries it is no surprise that Trains run vacant mostly on certain days due to weather conditions.
So your contention has Emotion, Drama, excitement, but it is not Valid that Easeten Railway is Faking the WaitList and Charts.
Still you have chance to verify this again, by seeing the ticket availability on This site and compare it on www.indianrail.gov.in. site.
Results are 'same' not 'almost' but same.
Yet any 'computer genius' can verify and support your claim how this is done.
without proof no one can be charged, without proof , every one is innocent, till fount guilty. This is the Law, in India, and this law is given by Britishers.
