Surat district sits on the Tapi river near its mouth, where the river meets the Gulf of Khambhat. Bharuch lies to the north, Narmada to the north-east, Tapi to the east and Navsari to the south. The district is made of Surat City, Choryasi, Olpad, Kamrej, Palsana, Bardoli, Mahuva, Mandvi, Mangrol and Umarpada. The Mumbai-Ahmedabad railway line and National Highway 48 run through it, and Surat railway station is one of the busy halts on the Western Railway. Goods come and go in every direction, and most owners never see the route their vehicle actually took.
The city is known for man-made fabric. Surat has dyeing and printing mills and a very large number of power looms, and cloth wholesalers cluster in the old market areas. Grey cloth goes out to processors, and finished fabric comes back in bales to the traders. Industrial areas at Pandesara, Sachin, Udhna, Kim and Palsana feed this chain with yarn, chemicals, dyes and machine spares. Surat is also a centre of diamond cutting and polishing, mostly in the Varachha area. Those workshops send small, valuable parcels, which need other tools, but the same belt also has loom owners, embroidery units and packing sheds that move heavy crates on trailers and hired tempos. A battery tracker on a crate or a trailer chassis suits that heavy side.
Hazira, on the coast west of the city, is the district's heavy industrial and port area. Steel, gas, power and engineering firms work there, and Hazira Port handles cargo for them. Trucks and trailers queue at gates, wait for loading and then run onto the highway. Inland, Bardoli, Mandvi and Mahuva form a farm belt where sugarcane, paddy, banana and vegetables are grown and cooperative sugar mills run in the crushing season. The Umarpada and Mandvi edge is greener and hillier. So a single district gives an owner three very different jobs for a battery tracker: fabric and machine freight in the city, container and bulk haulage on the coast, and cane trolleys in the villages.
