Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

The GE U25B was General Electric's first independent entry into the United States domestic diesel-electric railroad locomotive market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company; the U25B was developed following the termination of the consortium agreement.
The U25B (nicknamed U-Boat) was the first commercially successful domestic diesel electric road locomotive designed, built, and sold by General Electric after its split with the American Locomotive Company (Alco), a company dating back to the steam era. Along with Ingersoll-Rand, GE built the first viable American diesel-electric locomotive in 1928. GE had previously produced a number of prototype diesel switchers, in part with Alco. The GE Universal Series started production in 1956 and some 400 export locomotives were sold before the U25B was offered in the United States.
The U-Boat put GE on the road to becoming the top locomotive producer in the U.S., much to the chagrin of EMD. It introduced many innovations to the U.S. diesel locomotive market, including a pressurized car body and a centralized air processing system that provided filtered air to the engine and electrical cabinet, thus reducing maintenance. The U25B was also the highest-horsepower four-axle diesel road locomotive in the U.S. at the time of its introduction, its contemporaries being the GP20 (2000 hp) and the RS27 (2400 hp).
Though many were produced and sold, the only remaining U25B locomotives are in museums, as many were retired or scrapped at the end of their service life by the end of the 1980s.
Only one remains in operating condition. Southern Pacific 3100 is now on permanent exhibit at the Orange Empire Railway Museum in Perris, California. Built in 1963, this locomotive was first numbered SP 7508. Later numbered SP 6800, it became a goodwill ambassador for the railroad in 1976 when it was painted in an elaborate red, white, and blue color scheme in celebration of the nation's bicentennial; it was later renumbered and repainted in standard SP livery and was donated to the museum. The 3100 is fully certified to run on any of the nation's railroads and is frequently used as motive power for offsite work trains.
A second U25B locomotive is currently undergoing restoration efforts at the Illinois Railway Museum in Union, IL. Former Milwaukee Road engine number 5056 (built in 1965) is being both cosmetically and mechanically restored for operation on the museum grounds.
A third U25B locomotive is on display at the Western Pacific Railroad Museum in Portola CA. Engine number is 5057 and can be made operable.
New York Central #2500 is preserved in operating condition but lacking a cooling fan at the Lake Shore Railway Historical Society museum in North East, Pennsylvania.
Conrail 2510 was to be preserved by The Great Northeastern Rail Road Foundation, but the plans fell through and the engine is sitting in rough shape, in Glenmont,NY. It is currently owned by the NRHS. It was built as New York Central 2510 in May of 1964.
