Would like to know whether train no 52455 Himalayan Queen (Kalka - Shimla) is a connecting train for 12011 Delhi- Kalka Shatabdi. The reason behind this question is, the latter reaches Kalka at 11.45 AM and the former leaves Kalka for Shimla at 12.10 PM. Will Himalayan Queen wait in case Shatabdhi is late by say 30 or 45 minutes in reaching Kalka. Can I book by both trains in advance for the same day. Please help. Thank you.
