To answer your question, I don't think so. Even if it did fit, it would look very silly, and the outside of the locomotive will hang over the entire track (In the middle of the loco) Leaving most of the track visible in the middle of the loco. If the couplers are body mounted, you can forget about pulling cars. With a loco that size, even truck mounted wouldn't do much. You definitely wouldn't want it if you want your layout to look realistic. Most factories will recommend 22" radius curves on most 6 axles because not many companies make snap track into curves of a higher radius and they want entry level model railroaders to be able to run those big engines without flex track. But that doesn't mean it'll work nor look good. For me, I wouldn't get that diesel with anything less than 26" curves. That is still kind of tight, but it is the largest radius curve that'll fit in a 5 foot wide space with about 5-7 inches of space between the track and the end of the table other than 28" if my math is correct: 28 degrees= 56 inches in diameter with 56 inches equaling 4.6 feet. Thats 6 inches between the track and the end of the table. You can fit a larger radius in 5 feet, but your track will come close to the edge of the table. But I could be off a little.
