Yes, "his smile derailed" could be interpreted as a metaphor. The use of "derailed" suggests that his smile has been thrown off course or disrupted in some way, which could be a metaphor for his emotional state or the impact of a particular event on his demeanor. It implies that something has caused his smile to falter or lose its usual brightness, conveying a deeper meaning beyond just a physical description of his expression. **

The cause of the delay due to a derailed train is typically the physical obstruction of the tracks by the train cars that have come off the rails. This obstruction prevents other trains from passing through the affected area, leading to delays in the train schedule. Additionally, the process of clearing the derailed train, inspecting the tracks for damage, and ensuring safety before resuming operations can also contribute to the delay. **

The popularity of cycling or skiing can vary depending on the location and time of year.

The excitement level of ice hockey versus soccer is subjective and can vary depending on personal preferences. Ice hockey is known for its fast-paced, physical nature with constant action and scoring opportunities.

Both sports have passionate fan bases and offer unique thrills, making it difficult to definitively say which is more exciting. **

It is highly unlikely that soccer will replace American football, basketball, baseball, and ice hockey as the most popular sports in the USA. These sports have deep-rooted cultural and historical significance in American society, and they have large and dedicated fan bases. Additionally, American football, basketball, baseball, and ice hockey have well-established professional leagues and infrastructure in the USA, which would make it difficult for soccer to overtake them in popularity. While soccer has been growing in popularity in the USA, it is more likely to continue to coexist alongside these other sports rather than replace them. **

Ice hockey is often perceived as more brutal than soccer due to the physical nature of the sport, which includes body checking and fighting. However, both sports have their own unique physical demands and risks of injury.

Ultimately, the level of brutality in each sport can vary depending on the intensity of the competition and the actions of the players involved. **

It is unfair and inaccurate to label all Germans as Nazis or right-wing extremists simply for criticizing the asylum policy. Germany has a diverse population with a wide range of political beliefs and opinions. Criticizing the asylum policy does not automatically equate to holding extreme right-wing views.
