With a crash both cab windows were splintered to fragments. The young engineer of No. 999 was nearly swept from his seat as there poured in through the gap a volume of snow.

They had struck an immense snowdrift obliquely, but the fireman’s side caught the brunt. As the powerful locomotive dove into the drift, the snow packed through the denuded window-frame at the fireman’s seat like grain into a bin. A solid block of snow was formed under the terrific pressure of the compact. It lodged against the coal of the tender with a power that would probably have crushed the life out of a person standing in the way.

“Whew!” shouted Fogg. “Lucky I ducked.”

Ralph stopped the engine, which had been going 255 slower and slower each minute of the past hour. They had gotten about half the distance to Rockton. Long since, however, both engineer and fireman had fully decided that they would never make terminus that night.

They had left Stanley Junction under difficulties. The snow was deep and heavy, and there was a further fall as they cleared the limits. There was no wind, but the snow came down with blinding steadiness and volume, and at Vernon they got the stop signal.

The operator stated that the line ahead leading past Fordham Cut was impassable. The passenger was stalled ten miles away, and orders from Rockton were to the effect that the Overland Express should take the cut-off. This diverged into the foothills, where there were no such deep cuts as on the direct route, and where it was hoped the drifts would not be so heavy.

Neither Ralph nor Fogg was familiar with their new routing. For an hour they made fair progress. Then they began to encounter trouble. They did not run a yard that the pilot wheels were not sunk to the rims in snow. Landmarks were blotted out. As they found themselves blindly trusting to the power of the giant locomotive to forge ahead despite obstacles, they were practically a lost train. 256

It was now, as they dove bodily into a great drift choking up an embankment cut, that they realized that they had reached a definite angle in their experience of the run, and were halted for good.

No. 999 barely pushed her nose far enough out of the enveloping drift, to enable Ralph by the aid of the glaring headlight to discern other drifts further ahead.

“We’re stalled, that’s dead sure,” declared Fogg. “Signal the conductor and see what the programme is.”
