Highball: Railroad Ball Signals, Slang & Meaning

Last revised: September 6, 2026

A highball is a proceed. In the hardware sense it was a ball hoisted to the top of a mast: clear to go. In the language that outlived the mast it is the conductor’s or dispatcher’s word that the railroad is yours—leave town, run the timetable, do not linger. Railroaders still say it on the radio. The drink of the same name is a different story.

The live copy that sat here was Chat padding: a “rich tapestry of traditions,” no timetable rule, and a caption that treated a 1976 Boston & Maine extra at Whitefield, New Hampshire, as the place the word was invented. Whitefield is the famous late survivor, not the origin. Ball signals of this type gave American English the word. The signals hub is the encyclopedia of aspects, blocks, and PTC. This page is the ball and the slang.

Boston and Maine GP9 1720 and GP7 1575 at the Whitefield New Hampshire ball signal July 22 1976

Boston & Maine GP9 #1720 and GP7 #1575, bound for Berlin, have a clear "High Ball" as they set out cars for the Maine Central at Whitefield, New Hampshire on July 22, 1976. This early type of signaling system is where the term "high ball" originated. Ronald Johnson photo.

At a glance

Item	Detail
Word	Highball: proceed; the way is clear. Also a fast run, or an engineer who runs that way
Hardware	A painted ball (or balls) on a rope and pulleys, hoisted on a mast. Ball at the top = proceed for the move the rule named. Ball down = stop / do not occupy
Where they lasted	Especially at New England diamonds and junctions, into the steam-to-diesel years. Most were gone by the mid-1960s
Famous survivor	Whitefield, N.H., B&M Berlin line × Maine Central Mountain Division. Mast dated to 1875. Last ball signal in regular American railroad service
Whitefield rule (late B&M special instruction)	One ball (or one red light): B&M may cross the MEC. Two balls (or two red lights) at the top: MEC may cross the B&M. Crews stopped short of the diamond and set the balls themselves
Not this page	Block signals, semaphores, CPLs, PTC. See railroad signals, semaphores, B&O CPLs
Not a cocktail history	The whiskey-and-soda highball is a separate American drink name from the 1890s. Do not treat the railroad as proven inventor of the glass

Whitefield indications from Boston & Maine employee special instructions as quoted in period operating practice (including SI 696a in a 1978 timetable). Solomon and the Waumbek Junction marker agree on one ball for the B&M, two for the MEC. Information compiled September 6, 2026.

How a ball signal worked

Before night color-lights and before most roads had a continuous pole line, a train needed a mark it could see in daylight from a distance. A ball on a mast is about as simple as a signal gets: a sphere, a rope, two pulleys, and a man who knows the rule. Raise the ball to the masthead and the engineer reads proceed. Leave it down and he reads stop. At a quiet station that could mean “the agent has the train order ready” or “the siding is yours.” At a diamond it meant “you may occupy the crossing.”

That is the origin of the word. A high ball was the proceed indication. Railroad slang kept the high and dropped the hardware. Brian Solomon, in Railroad Signaling, puts it in one sentence: the use of ball signals gave way to the term “highball,” which meant proceed, and in casual speech railroaders still use it when it is time to leave the station. Another old use described an engineer who ran fast.

Balls were not a national standard aspect system like a three-position semaphore. They were local plants, often at grade crossings of two railroads, drawbridges, or stations, with the meaning written in the employee timetable for that spot. Complex junctions used more than one ball. Solomon notes a Boston & Maine multiple-ball plant at White River Junction, Vermont, where the number of balls (or lights) displayed authorized different moves across the diamond; four balls in one published view authorized a movement from the Central Vermont or from the south. B&M Time Table No. 41, June 21, 1946, told enginemen approaching a ball-protected crossing to stop within 1,000 feet; if the signal was right, they could proceed.

They were not the first railroad signals, and they did not vanish in 1840. Some popular sketches compress American ball signals into a handful of 1830s years. New England diamonds kept them into the diesel era. Semaphores, then color-lights and interlocking, took the work. The word stayed.

Whitefield, New Hampshire

The photograph on this page is Whitefield. The Boston & Maine Berlin line crossed the Maine Central Mountain Division at a diamond in the village. A ball mast, dated to 1875, protected the crossing. It was a crew-operated plant, not a tower with a leverman on every trick. A train stopped short of the foreign road—500 feet in a late B&M special instruction, 1,000 feet in the 1946 rule Solomon quotes—and a trainman set the balls for his railroad, then restored them after the move.

Late special instruction 696a, as crews remembered it: one ball or one red light allowed Boston & Maine trains over the Maine Central; two balls or two red lights at the top allowed Maine Central trains over the B&M. The Waumbek Junction marker now at the Conway Scenic Railroad in North Conway says the same thing for that plant: one ball at the masthead for the B&M, two for the MEC. Waumbek (Jefferson, N.H.) was another B&M/MEC crossing; its mast was relocated for display. Whitefield’s stayed in place.

Ronald Johnson caught GP9 1720 and GP7 1575 there on July 22, 1976, bound for Berlin, setting out cars for the Maine Central with the balls showing a proceed. That is a highball in the original sense, on one of the last masts that still meant it. Solomon called Whitefield the last such signal in regular service. The Mountain Division and the Berlin line both faded under Guilford and successors; the New Hampshire Central and related short-line fragments still touch the village. The mast remains a pilgrimage for signal fans. It did not invent the slang. It outlived almost every other American example of the hardware.

The word after the hardware

Once the balls came down, the word did three jobs.

Proceed. On the radio it is still the short way to say the train may leave: brakes released, inspection done, orders complete, highball. A conductor on the ground or in the cabin car gave the same meaning with a lantern or an arm—the high proceed signal that crews still call a highball. It is not a synonym for “all the air is in the train.” You do not highball with the brakes stuck. You highball when the railroad is yours.

A fast railroad. To highball a subdivision is to run it at the maximum authorized speed without extra stops. A highball artist was an engineer who kept the time. That use is as old as the steam timetable. It is not a license to run too fast. The word always sat inside the rule: proceed at the speed the signal, the order, and the timetable allowed.

Not a signal aspect on a modern color-light. A CTC dispatcher does not “highball” a plant in the rulebook sense. Crews still say it to each other. The glossary entry is the one-line version: proceed at normal speed; the railroad is yours. From ball signals: the ball hoisted high meant clear.

The cocktail, briefly

A highball in a glass is whiskey and ginger ale or soda over ice, an American bar name from the 1890s. Writers have tied it to the railroad for a century: the ball went up, the train went, the drink went down fast. That is folklore. The railroad word is older than the cocktail in railroad use and does not depend on the bar. This page does not prove the drink came from the mast, and it does not need to. If you came here for the glass, the railroad meaning is the one that still moves trains.
