Railway Minister Piyush Goyal on Tuesday said that fixing automatic data loggers at 98 places on different railway routes had helped increase train punctuality to 72 per cent in August compared with the past few months.

"We put up automatic data loggers at 98 places. As the new devices became operational from April 1, as many as 94 trains were found running late by more than six hours, but the numbers decreased to 87 in May and 67 in June," he said.
