Transit means "cross your local meridian".

(i) The passage of Mercury, Venus, or a minor planet across the disc of
the Sun.
(ii) The passage of a planet's moon across the disc of the parent
planet.
(iii) The passage of a planetary feature (such as Jupiter's Great Red
Spot) across the central meridian of the planet.
(iv) The passage of an object across the observer's meridian (see
culmination).

Hi there. You posted:

What's the difference between transit and culmination?

Culmination is for objects which do not set anywhere on the local horizon (ie:
circumpolar stars). Upper culmination is when the star is highest above the
horizon (ie: it appears higher in altitude than the north celestial pole) and
on the meridian, and lower culmination is when the star is on the meridian but
below the north celestial pole. Clear skies to you.

Paul Schlyter:
Second, for circumpolar objects there is no requirement that their
altitude at upper culmination should be higher than the altitude of
the celestial pole. As an extreme example, consider an observer at
89 degrees N latitude and an object at +3 degrees declination: to
that observer, the celestial pole will be 89 degrees above his
horizon, and that object at +3 degrees declination will be 4 degrees
above his horizon at upper culmination and 2 degrees above his
horizon at lower culmination (ignoring atmospheric refraction). To
him, everything north of +1 degree declination will be circumpolar,
but very few objects will appear higher in his sky than the north
celestial pole.

This example is both clever and fascinating. I fear, however, that if I
were at +89 I would freeze to death before I had to time to fully grok
its elegance.

You must come from one of THOSE towns? It's a means of shuffling
people around a town by little trains that run under the street (oh,
sure) or on stilts over the streets (yikes!). These trains got NO
ENGINE in front and make a horrendous noise when under steam.
You get onto them by climbing down tiny dark ilthy staris or
climbing up tiny dark filthy stairs. You pay the fare by buying a
token or magnetic ticket and putting it in a turnstile. You get into
the train with thoudands of other perfect strangers and smell each
other stupid.
You should move to a town with transit.
