As a Transformers enthusiast since my childhood, I have read almost every Transformers comic published in the last 25 years, and I'm sorry to say that this is one of the worst. The scenario was promising enough: the Transformers awake in 1884 instead of 1984 and therefore end up assuming forms of that era. It's a good idea that was poorly executed.
Some of the weaknesses are minor even though the mistakes themselves are obvious: for example, the Decepticons never use flying technology and the entire plot is based on them building a railroad line and reaching New York City in their "Astrotrain", thus tapping the electricity that has just begun production.
More severe is the lack of character development: of the Transformers characters, only Bumblebee and Starscream are written in such a way that we can identify with their motives and characters. The humans get a slightly better treatment although even the main human, John Henry, a railroad builder befriended by the Autobots, does little other than be a noble character. The story ends very abruptly with no real wrap-up.
Given the promise of the original premise, I hope we see more series like this in the future, but Chuck Dixon is probably not the right person to write them. Machines that transform into robots are not enough to make a story: the Transformers have always been popular because writers managed to breathe life into them. A change of century alone won't do it.
