Why do you think neruda syas that people would be ''uneasy'' locomotives?

Pablo Neruda likely describes people as "uneasy locomotives" to convey a sense of restlessness and the burden of moving forward in life. Just like locomotives that carry heavy loads and must navigate tracks, individuals often feel the weight of expectations and desires, leading to a constant state of tension. This metaphor suggests that, despite their power and capability, people may struggle with unease as they pursue their journeys. Ultimately, it reflects the complexities of human existence and the emotional challenges that accompany progress.
