There were no major car manufacturers in the country 3 decades ago. It all started with Maruti Suzuki in the 1990s and today, in 30 years we have come a long way with 10s of Indian brands out there on the Indian roads. These vehicle manufacturers have factories across the country and overseas brands have numerous assembly plants across the country. However, after manufacturing, the next step is to move these vehicles to the retailers in towns big and small across the country, so the general public can purchase them. Car Transport by Train is the cheapest and the fastest way for these businesses to move their product, these cars in bulk. If the cars are moved via roadways, then a number of trucks will be required and it will be a very expensive option.
Trains are regarded as a safe way for traveling for most people who journey across the country regularly. This is true for goods too. Trains carrying goods rarely stop at any station, apart from the destination. Your cars will usually be loaded into containers, which will be then loaded into trains. Hence you will need the services of ICDs (Inland Container Depots) where the containers get loaded and unloaded. Indian car models are being exported to other countries too. However, these are mostly third world countries and they have shown more interest in Indian bikes than Indian cars. For overseas exports, again containers will be used, but in this case, they will be moved via ships.
It’s not just businesses but individuals too can get their vehicles moved via trains. The big car manufacturers can either arrange all the logistics themselves or they can hire Vehicle transport service in India to do this for them. They will be spending some money but you will be passing on this difficult work to experienced organizations which will be able to arrange everything better than you.
