Can someone please tell me how to get an Electron card?

Ask your bank to downgrade your existing card. Join a bank with an
account that offers Visa Electron. Most banks don't offer it now.

Airlines and
railway companies don't charge an extra fee for payment by Electron card
but they do for payment by debit and credit card.

By the way, what is the logic for this discrimination?

It is a 'credit' card, but it does not offer credit, you are not allowed
to go into debt with it, you must have the full funds for a transaction
in your account if you wish to use the card.
