Choo-Choo Connection

This is a sketch of a train: the front half is a more old-fashioned type while the back half is a more modern maglev type. My realistic object used in this sketch is a USB-C to USB-A adapter. I chose this object from my desk of random objects. I wanted to use something that was irregular, not circular or linear, to make my sketch more interesting. Once I selected the object, I thought what does this look like? To me, it looked like a cargo segment on a train (also possibly heavily influenced by the loud trains outside my dorm). At first, I was going to make a train with the connector as one of the freights, but then I realized I could use it as its actual purpose: a connection point. From there, my idea stemmed that I would draw one half as an old coal engine and one half more modern since each side of the USB adapter transfers at different speeds. So this drawing not only literally represents the USB adapter being used to connect two different (train) segments, but also displays the different speeds.
