Khairthal also has one of the biggest grain markets in Rajasthan.
Khairthal is well connected by both rail and road. It lies on the Delhi-Jaipur Railway, 130 km from Delhi. Most trains on this route stop at Khairthal, including the Ashram Express, Malani Express, Pooja Express, Kathgodam Express, Katra Express, and Yoga Express.
The town is connected by road to National Highway 8, the Jaipur Delhi Expressway. Connecting points on the NH8 from Khairthal are Kotputli (via Bansoor) on the Jaipur side, and Dharuheda via Kishangarh Bas on the Delhi side. A new highway project is under construction from Kishangarh to Kotputli via Khairthal, which will be on its way by 2014. A new Jaipur-Khairthal express was opened after seeing the number of daily passengers. Recently, a Jaipur-Delhi AC train has been opened with Khairthal as its one of its stops.
