The old silk-route from China to India and other countries for trade was famous and continued for centuries. It does not exist now.
A new silk route or Silk Road Train has now been established between Britain and China. This is a direct train starting both from Britain and China and reaching the other end. The first China-Britain was operated a few days back. The train from Britain to China started on 10th April, which will cover 12,000 km journey in 18 days and will go through France, Belgium, Germany, Poland, Belarus, Russia and Kazakhstan before reaching China. The freight train have 32 containers with a length of 600 metres. (input from Hindu, 11-04-2017).
