Scope of Work:	Underground anomaly mapping using Ground Penetrating Radar (GPR) up to the depth of 1.5 m.
Location:	Vrindavan and Ajhai, Uttar Pradesh.
Client:	North Central Indian Railways.
Equipment:	GSSI SIR 4000 equipped with 400 MHz center frequency antenna.
Summary:	A Ground Penetrating Radar (GPR) survey was executed for an approximate rail track length of 1990 m and 1592 m of the down line in Vrindavan Railway station and Ajhai Railway Station respectively, Uttar Pradesh in the month of November 2023. The objective of the project was to use non-destructive GPR technology to map potential undesired objects, such as rail pieces, concrete slabs, utilities, voids, or caked ballast within the area. The presence of scrap in the ballast has been causing issues during the screening process with the Ballast cleaning machine (BCM), leading to reduced output and damage to existing cables. This survey aimed to locate and generate a map of the scrap materials without causing any destruction. As this can help the IR authorities to plan the smooth movement of BCM and, assists in making informed decisions regarding maintenance, repair, and optimization of the railway track infrastructure. The GPR survey has been executed using 400 MHz center frequency antennas mounted with GSSI SIR 4000 GPR systems.
