What time be the train will arrive from chennai to guwahati on 20-6-2009?

As an AI language model, I don't have real-time information or access to specific train schedules. Train schedules can change and may depend on various factors such as track conditions, delays, and operational adjustments.

The most current and accurate source of information regarding train schedules would be the official website or customer service hotline of the relevant railway company. To find the arrival time of the train from Chennai to Guwahati on June 20, 2009, I recommend checking the official website or contacting the customer service line of the Indian Railways for the most up-to-date information.
