As a general rule, any steam loco with 2 pilot (leading) wheels is designed for medium-low speeds (freight). Fast engines (passenger) had 4 leading wheels. These wheels weren't just decoarative, they had functions. 2 wheels helped lead the loco into curves, and 4 wheels did so even better.
There were exceptions, of course, and of course you won't get struck by lightning if you break the "rules".
Another thing that seems obvious to old codgers like me, but seems to be unknown to some younger folks is that pulling capacity is (roughly) proportional to the number of driving wheels. A 0-8-0 switcher could move just about the same number of cars as a 4-8-4. Not as fast (the switchers drivers were smaller) nor as far (the boiler on a switcher couldn't generate enough steam long enough), but they could move looong strings of cars!
One episode of the History Channel's Trains Unlimited series stated that the Baldwin 2-8-0 was designed to pull 30 loaded freight cars at 30 miles per hour.
There's a wealth of information about the 2-8-0 on Wikipedia
http://en.wikipedia.org/wiki/2-8-0
A lot of 2-8-0s were the primary or only form of motive power for many shortlines and branches all accross the country and so did all duties required along the line.
In it's final decades the 18.5 mile long Buffalo Creek & Gauley out of Dudon WV (Accross the river from Cass WV) ran three 2-8-0s:#4, #13 & #14. One Baldwin and two ALCOs respectively.
They used them in an alternating fassion: one in the shop, one fired up as reserve for the day and one to do the day's work. They hauled nearly unit coal trains down from Widen WV and the Rich Run Mine. They also had mixed freight which served communities along the way, including lumber out of the mill at Swandale. The line had three pasanger cars running into the 1940's, an old wooden coach and two combines which most believe were ex-Pennsylvania cars with port hole windows.
The BC&G ran steam until it's closing in 1963 and all three locomotives are still around in various states of service of restoration.
Wow, there's a lot of bad information in this thread.
The 2-8-0 was a passenger locomotive because it had larger drivers.
The Bachmann Spectrum 2-8-0 (which is the model we're talking about) has 63" drivers, which is a pretty typical driver size for Mikados. The drivers might be a tad large for the run of the mill Connie, but the model is of a LARGE 2-8-0.
The Illinois Central used the 2-8-0 's on branch line runs and I have watched them work trains of forty or more cars as a regular assignment in that service.
Actually, these engines (the model is based on the IC's 942 and 900 series engines) were originally built as mainline superpower in 1909. By the 1920s they had been bumped to secondary mainline service, mostly as local switchers and "turn" engines. By the time they were rebuilt into the 900 series, they had been re-upgraded to run trains on secondary mainlines as well as branches with heavier weight allowances (the IC maintained a small fleet of tiny 2-8-0s and 2-6-0s for true branchline service)
As far as I know all North American 2-8-0's were designed to be freight engines, but some were used on occassion for passenger service
Some turn of the century 2-8-0s WERE designed with passenger service in mind. The TStL&W (Clover Leaf) settled on the 2-8-0 as their standard engine some time around 1900, and by the time of their merger with the NKP in 1924 had an almost all 2-8-0 roster. Those engines pulled both their mainline passenger trains and their mixeds, and had relatively large 64" drivers. The NKP used the engines to pull passenger runs into the 1940s.
What's this nonsense about "light" and "heavy" 2-8-0s? ALCo and Baldwin both catalogued a range of 2-8-0s from very small to very large, none of which were described in contemporary sales literature as light or heavy.
Except that the model in question represents an IC engine, built by Baldwin, but to the specifications of the IC's mechanical department. Baldwin had nothing to do with the engine design. Moreover, the engine was a Harriman-Standard design, which DID have light and heavy engines. The model is of a Harriman heavy 2-8-0.

An example of the rule exceptions were the SP's 4-8-0s. They were used for freight hauling. SP kept them around for over half a century because they could be used on light-rail branchlines although they were otherwise obsolete. (The 4-8-0 had one more axle to spread the engine's weight than the 2-8-0.) Another example: some railroads purchased large-drivered 2-6-2s initially for passenger service. Further, 2-8-0s were often used on excursion trains since the 1950s.
Another general rule was the passenger locos had one or two trailing trucks under the firebox because such locos could generate more steam (horsepower), necessary for sustained, high-speed service. A major exception was the 4-4-0.

The SP's 4-8-0s were originally built as compound locomotives, and the four-wheel pilot truck was there to support the machinery required by the compounding. (IIRC, SP's 4-8-0s were originally cross-compounds.) When they were rebuilt as simple engines, they retained the four-wheel pilot truck.
Because of limited driver size, 4-8-0s were rarely built as passenger engines. And very typically, were originally built as compounds of one type or another.

Railways in Argentina, Italy, France, Norway, Austria, Yugoslavia, Czechoslovakia, Hungary, Poland, Turkey, Portugal, Spain and Sweden all had big-wheel passenger 4-8-0s. The last French 4-8-0s, Chapelon's 240Ps, were among the fastest, most efficient and powerful steam locos ever built. Elsewhere - Asia, India, Africa, South America, and Australasia - 4-8-0s were usually mixed traffic engines.

When I write, I take North American practices for granted; I am only minimally acquainted with non-North American railroading.
OTOH, one of the US locomotive builders built a fleet of 4-8-0s for the National Railways of Mexico which were used primarily in passenger service. They were essentially 4-6-2s with a set of drivers replacing the trailing truck. But these engines were built in the 1920s-1930s, whereas most US 4-8-0s were built in the last decades of the 19th century. The Mexican engines had drivers between 60" and 70" (I can't remember the exact size and I am away from my books), while few US 4-8-0s had drivers that were even that big. (And most 4-6-2s had drivers greater than 68".)

I know that most of the later 4-8-0s used by Southern Pacific were originally built as cross-compounds. Monon's 4-8-0s were also built as compounds. I do not remember if Norfolk & Western's 4-8-0s, which was the largest fleet (over 200 engines) of 4-8-0s in the US, were originally compounds, but I would be surprised if they weren't. I do not doubt the earliest 4-8-0s were built as simple, but most of those came and went before the 1920s.
But most, if not all of the 4-8-0s that survived until dieselization had been rebuilt as simple engines, often with superheaters.
Again, I don't presume to speak on the practices of railroads outside of North America.

Maybe on short lines and branches that had a traffic profile that was primarily freight oriented. However if the traffic balance was closer to 50-50 then 4-6-0 with medium height drivers, 57" to 66", was far more likely to be the choice.

Perhaps the statement is true in the east, but in the West there were prejudices against the 4-6-0 arrangement on several railroads. Then there were lines that really liked their 4-6-0s. Prejudices and judgements of the engineering departments were a strong factor in what motive power railroads bought.
