Sam Fisher- Train in a Sandstorm

  “Keep him busy,” cried Fisher, who crawled forward, slid under the upper deck railing, seized one of the grab irons, then allowed himself to slide down, off the right side of the container. He descended on two more grab irons until he was able to latch both hands onto the base of the upper deck railing. Now, with his legs dangling freely, he worked himself sideways across the deck, concealed from the agent’s view, while Briggs squeezed off another volley of suppressing fire, the MPX booming over the rattle and clack of the train.

  Fisher continued slipping across the container until he reached the end and once more shifted down to the grab irons. He lowered himself between the cars, crossing over the coupler receiver hitch and reaching the next ladder.
...

  Fisher scaled the ladder and once more began skimming his way across the side of the container—

  But without warning the train lurched forward, thundering at what must be full speed now, the diesel locomotive running at least sixty-five miles per hour. Fisher felt his grip falter and he tensed, fighting to pull himself higher and keep moving, each release of his gloved hands coming in smooth, practiced strokes. All those pull-ups and all that French Parkour training focusing on using momentum to breach obstacles always paid off.
...

  Fisher reached up, slapped a gloved hand on the bottom rung of the upper deck’s railing, then, hanging by one hand, he drew his Five-seveN and swung up a leg, latching it around a support post. As he forced himself back onto the upper deck, sliding on his belly, he brought up his pistol and watched as the agent chanced another look.

  Bang. Fisher shot him in the eye. “Briggs, move up!”

  The wind was so fierce now, the sand battering them so violently, that Briggs could only stagger his way across the deck, keeping both hands latched onto the railing.
...

  “Let’s do it.” Fisher slid around the side of the container and stepped onto the lower railing, merely a thin bar and protective skirt for the wheels. The grab irons were too high to reach, and there was no way he could balance himself on that rail without hand supports and with the train dieseling hard at sixty-five miles an hour, so he clutched the rail, then allowed himself to fall forward, swinging beneath it, ankles latched, and he began a swift, hand-over-hand approach, with the cacophony of the wheels at his side until he reached the midsection, the wind passing under the container and coming in short bursts, the sand hissing and getting into his mouth, ears, and nose. Ignoring the blood rushing into his head and the fire in his pectoral muscles, he grimaced and slid even faster.
