I shipped my bike from SBC to CCT by train a couple of weeks ago . Here are a few important things for you to know.
Luggage booking: You can book it as a luggage so that it can be shipped along with on the same train. But booking is not allowed from every random station and should be confirmed with the luggage office. This costs a bit more than a parcel, and you only have to provide the labour and personally make sure that the bike is loaded. All this will cost a bit more.
Parcel...
more... booking: This was what I followed. This is a cheaper option. It cost me 1900 Rs for shopping my bike and 3 other large boxes ( about 200 kg total). There will be people available outside who will pack it for you and also drain all the petrol ( this is absolutely compulsory and they can even reject the bike if the tank is not empty). Usually they charge about 300-400 rs for the packing. After the packing is complete , fill the shipment form, carry a photocopy of your RC card (registration documents), driving license, one address proof and your bike insurance ( this is not mandatory though). You will be asked to quote a value for your bike. Based on the value you quote, some amount will be charged as insurance.
After this is complete, make sure that the loading staff there correctly put the address on your bike. (they'll also ask for some money, usually around 200 Rs). The bike will be shipped within 3-5 days. ( mind got shipped on the next day itself). Once it reaches the destination, you'll get a call from the parcel office. Collect it within 6 hours as beyond that you'll be charged 10Rs/hr. Show the bill you have been given at the booking office, to collect it at the destination. DONT lose the bill at any cost!
