Derailed train in Muntinlupa because of heat?

From gmanetwork.com:

A passenger train was derailed in Muntinlupa City shortly before noon Tuesday, with the Philippine National Railways suspecting the summer heat may be have caused the incident.

PNR spokesman Paul de Quiros said no one was initially reported injured, adding teams had been sent to the site to clear the area.

“Initially, ‘yung sabi na dahil sa sobrang init may rail expansion (Initial reports indicated the rails expanded because of the summer heat),” De Quiros said in an interview on dzBB radio.

He cited initial reports indicating the incident occurred at about 11 a.m. between the Sucat and Alabang areas in Muntinlupa City.

Asked if any of the train’s passengers were hurt, he said there were none.

He added some of the train passengers eventually took other forms of public transportation.

De Quiros said it was lucky the train operator saw something wrong with a portion of the railroad tracks and decided to slow down.

“Naramdaman ng driver kaya nag-slow down siya. Na-derail nang kaunti,” he said.

Since April, Metro Manila had been experiencing high temperatures, which reached as high as 36.7 degrees in Manila last Sunday.

The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said it is possible temperatures may soar even higher this month. — LBG, GMA News
