MEXICO CITY, Dec 30 (Reuters) - Mexico's President Claudia Sheinbaum deferred questions on Tuesday about the record of a passenger train that derailed over the weekend, killing 13 people and injuring 98 others, the latest in a series of accidents that have put pressure on her government to improve the safety of flagship projects.
The conductor of the train, who survived, has been taken in for questioning, and opposition lawmakers have called for an investigation.
