When an extravagent theme park was in the planning stages in 1995, the driving forces behind it were Anheuser-Busch, the Tussaunds group and Universal Studios. Thus, Port Aventura opened with two coasters straightaway. One of them was the famed Dragon Khan, manufactured by Bolliger & Mabillard and specially designed to have eight inversions. The other was none other than Tren de la Mina, better known as El Diablo. Diablo was a project from Arrow Dynamics, and takes riders on a journey through an old silver mine thanks to theming. Its name means "the devil" in English, and the ride features three medium sized lift hills in its three fourths of a mile of winding track. Diablo opened with the park on May 2nd of that year, and was placed in the park's Mexico section. Diablo winds itself under and over Silver River Log Flume, one of the park's water rides, and features two tunnels which travel under the park's railroad. The ride also travels over paths and even features a swooping pre lift section which circles the inside radius of the ride's final curving drop, a unique feature for an Arrow Dynamics mine train. In fact, the entire ride is unique for an Arrow Dynamics mine train as it plunges riders through various turns dodging the log flume, and later a tight helix finale.

Diablo itself features tan steel track with wooden supports, and leads riders through that track in locomotive style trains themed to resemble the very trains which ventured through the old silver mines. As previousy mentioned the ride features three lift hills which each vary in their size, the highest being 54 feet above the landscaping below it. The ride's station is decorated in a fitting mine style, adding to the ride's extensive theming. That theming is part of what makes Diablo a very interesting mine train coaster. And as also previously stated, the coaster features 3,306 ft (1,008 meters) of track, which makes for a 3 minute and 10 second experience. Quite the duration for a mine train, and quite an experience.

That experience begins when the train is released out of the station, plunging down a large dip past the finale of the ride which will be encountered later, and through the ride's first tunnel. Exiting the tunnel at a brisk pace, the track leads into the pre-lift section which begins by sending riders though a downwards curve which leads into a straightaway. Another curve gives way to the first fifty three foot lift hill. Upon exiting the lift hill, the train negotiates two left hand turns which travel over the two splashing portions of the Silver River log flume. Then the train is whisked down to the right underneath one of the flume's drops, and up over yet another portion of the flume a final time before negotiating a left swooping turn and ending up on the second lift hill. The train travels up thirty seven feet this time, and is soon after lead though another left hand swooping curve. Briefly encountering a set of trim brakes, the train is whisked past a building on the left through a right hand turn, and immediately leads into one of the last brake sections of the entire ride as the train comes to a brief halt.

The anticipation sets in as the train slowly begins the final fifty four foot climb up the third lift hill, traveling over a pathway below. As the train disengages the lift, it is sent down a right hand swooping drop which encircles the pre-lift section the train passed through minutes before. Whisked through the second tunnel, the train passes through a tight helix which makes for an exciting finale as the train is finally led back into the station, completing the three minute and ten second ride. Riders have just braved and survived an exciting trip through the silver mines, and Diablo certainly delivers that experience well as it proves true each time its slogan as "el tren de la mina".
