The next day, Ethan rushed to his room, eager to see what his magical train would show him next. He nudged the little locomotive, and just like before, the shimmering light returned, and his wall became a bustling, historical scene.
Today, the workers were in a very tricky spot: high up in the mountains! The peaks looked so tall that they seemed to tickle the clouds. How could a train ever get through such huge, rocky walls?
Ethan watched as men with strong arms and determined faces began to chip away at the solid rock. Pickaxes swung, and shovels scraped, but the mountain was tough, tough, tough!
Then, he saw something new. Men carefully placed long, dark sticks into holes they had made in the rock. Ethan's eyes grew wide. What were those?
Suddenly, there was a loud, rumbling 'BOOM!' The sound vibrated through his very floor, and a cloud of dust and small rocks exploded from the mountain. It looked a little scary, but the workers seemed to know exactly what they were doing.
To make tunnels through huge mountains, workers had to use a special powder called 'dynamite'. It made a big boom that broke the hard rock into smaller pieces, so they could clear it away.
Little by little, chunk by chunk, the mountain began to open up, revealing a dark hole. This was going to be a tunnel! A place where trains could go right through the mountain, instead of having to climb all the way over it.
Ethan saw lanterns flickering deep inside the growing tunnel, as men worked tirelessly, even in the dark. It was a very hard job, and sometimes even dangerous, but they kept going, day after day.
