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 !

A terminal headshunt is a short length of track that allows a locomotive to uncouple from its train, move forward, and then run back past it on a parallel track. Such headshunts are typically installed at a terminal station to allow the locomotive of an arriving train to move to the opposite end of (in railway parlance, 'run around') its train, so that it can then haul the same train out of the station in the other direction.
The term headshunt may also refer to shunting neck or shunt spur: a short length of track laid parallel to the main line for the purpose of allowing a train to shunt back into a siding or rail yard without occupying the main running-line.
A run-round loop (or run-around loop) is a track arrangement that enables a locomotive to attach to the opposite end of the train. This process is known as "running round a train". It is commonly performed to haul wagons onto a siding, or at a terminal station to prepare for a return journey.
Although a common procedure when the majority of trains were locomotive-hauled, the manoeuvre is now comparatively rare on public service railways. Increased use of multiple unit and push-pull passenger services avoids the requirement for dedicated track and the need for railway staff to detach and reattach the locomotive at track level. However, many heritage railways (in the UK, at least) deliberately incorporate run-round loops at each end of the running line, partly because train services are usually locomotive-hauled, and partly because the run-round operation gives added interest to visitors.
Stations which used to have run-rounds include:
Stations which still have run-rounds include:
