Rajasthan ATS and Sri Ganganagar police arrested Mahakdeep Kaur and Davinder Singh in Gurdaspur over the November 3 railway-track blast.
Police allege a Pakistan-based handler identified as Shah recruited Kaur through a romantic relationship and provided instructions, funding and the target location.
Investigators say the accused received ₹2.23 lakh and made two earlier attempts before the blast near 50 GB village.
