Not exactly T&P, but...
Have you seen the new Utah state quarter? For the first time in US history, the mint has put a train on a circulating coin. (Yes, I know that's hard to believe. Canada has featured a steam locomotive on some of its coins, but this is the first train on a US coin.)
The coin depicts the driving of the Golden Spike and the completion of the first trancontiental railroad, which of course, happened at Promontory Point, Utah, in 1869. The coin's design is reminiscent of the famous photograph of the two engines from the Union Pacific and the Central Pacific facing each other.
