Authorities believe that the dynamite found — Goma 2 ECO — is the same kind that was used in the terrorist attack that killed 191 people and injured over 1,400 on Madrid trains on March 11.
The 26 pound explosive, connected to a detonator with a 450-foot cable, was found by a railway employee 35 miles south of Madrid near Toledo. Experts successfully defused the device.
Although Friday was a busy travel day in Spain, with trains and highways full of people leaving home for Easter vacation, the state rail company RENFE said no train was close to the bomb when it was found, according to the Associated Press.
This is not the first bomb scare since the March 11 attacks. Three letter bombs addressed to media outlets were discovered Thursday night at a mail sorting office in Zaragoza. Spanish police disarmed two of the bombs and blew up the third.
Authorities have not named any suspects yet, though they believe the March 11 attacks were the responsibility of the Moroccan Islamic Combatant Group, an extremist organization with strong ties to al-Qaida. Fifteen people have been charged in that case.
Spanish army and police forces are checking other high-speed railway tracks for more explosives. Helicopters and army vehicles will be used to guard key lines.
