We may congratulate ourselves that this cruel war is nearing its end. It has cost a vast amount of treasure and blood It has indeed been a trying hour for the Republic; but I see in the near future a crisis approaching that unnerves me and causes me to tremble for the safety of my country. As a result of the war, corporations have been enthroned and an era of corruption in high places will follow, and the money power of the country will endeavor to prolong its reign by working upon the prejudices of the people until all wealth is aggregated in a few hands and the Republic is destroyed. I feel at this moment more anxiety for the safety of my country than ever before, even in the midst of war. God grant that my suspicions may prove groundless. Abraham Lincoln, Nov. 21, 1864

Following from DiogenesLamp link makes clear this is not a quote from Lincoln himself, but rather a Jesse W. Weik 1889 interpretation of Lincoln's law partner William Herndon's decades later interpretation of Lincoln, made while Herndon suffered alcoholism in the years before his death in 1892.
In fact, Lincoln worked for railroad companies and was not opposed to them on principle.
The quote itself sounds like 1890 era urban Progressives rather than 1860s rural Republicans.
