reserving a ticket for the shimla toy train

Hi. I'd like to reserve a ticket in april from kalka to shimla on the toy train.

I've registered for the online reservation site and have managed to pull up details about the 'himalayan queen' from delhi to kalka, but can't find onward details from kalka to shimla on the toy train itself.

I'm probably being really thick but if anyone can help....

Thanks

Try the search feature above, just enter 'Kalka' and you'll find a couple of recent threads with loads of detail.
