Koleje Pomorskie Sp. z o.o.

Updated: August 2026 – The first sighting abroad is quickly noted down. The question comes three years later: what was that station called again – with ł or with l, with ń or with n? Koleje Pomorskie Sp. z o.o. is a good occasion to tackle this underrated topic, because the company name itself already belongs to a family of names you can barely find reliably again without knowing the spelling.

What is Koleje Pomorskie Sp. z o.o.?

Koleje Pomorskie Sp. z o.o. is a Polish local passenger rail company. The name is built on the pattern common in Poland: “Koleje” means railways, the trailing adjective names the voivodeship. “Pomorskie” belongs to Pomorze – in English Pomerania, the region on the Baltic coast in the north of the country.

Voivodeship railways like this are typically run by the regional self-governments in Poland. Other companies can operate in the same area, such as the city-focused PKP SKM w Trójmieście or a private provider like Arriva RP. The station alone therefore never tells you who’s running the train. Alongside them, nationwide, sits the holding company Polskie Koleje Państwowe, whose name itself carries one of the special characters covered here, the ń.

Nine characters that change everything

The Polish alphabet contains nine letters with diacritical marks. They aren’t decoration – they’re letters in their own right, with their own pronunciation and their own place in dictionary order.

Character	Sound clue	Common simplification	Occurrence in a railway context
ą	nasal o	a	voivodeship names, place names
ć	soft “ch”	c	place names, company names
ę	nasal e	e	place names
ł	like an English w	l	Małopolskie, many place names
ń	soft “ny”	n	Gdańsk and related names
ó	like u	o	very common in place names
ś	soft “sh”	s	Śląskie, place names
ź	soft “zh”	z	rarer, but changes meaning
ż	like French j	z	place names, street names

The classic case is ł: it looks like an l with a stroke, but sounds completely different and is a letter in its own right. Write it as an l, and you’ve simply written a different name.

Research and archives: the double-approach strategy

Databases treat diacritics differently. Some normalise automatically, so a search for “Slaskie” also finds “Śląskie” – many others don’t. The consequence is simple: always try both spellings, and settle on the correct form as the lead variant in your own records.

How to organise this for the long term is described in the guide to building a photo archive for spotters; ongoing logging is covered in the article on keeping a sightings logbook.

From destination display to vehicle

The destination display names the route, not the company. The reliable identification comes from the data panel – and that’s language-independent: country code, hyphen, keeper marking, next to the twelve-digit vehicle number. How this number is structured is explained in the guide to reading the UIC number.

For the vehicles, the Polish class scheme also helps, since its first letter names the type of propulsion. Typical examples in local rail traffic are the electric multiple unit PESA Elf 2 and the diesel railcar family SA135 / SA136 / SA139. Which type is used where changes with procurement and diagrams. The Elf, incidentally, comes from PESA Bydgoszcz, one of the two big Polish multiple-unit builders.

Typing special characters without giving up

Knowing the characters is one thing, typing them is another. Anyone taking notes on their phone on the go has three practical routes – and none of them requires learning a new keyboard.

The most common mistake is the convenient one: typing the name “roughly” and planning to correct it later. That never happens. After the trip the context is gone, and “Gdansk” never automatically turns back into Gdańsk. Anyone who regularly collects Polish sightings should therefore set up the second keyboard layout once and be done with the topic for good.

A small habit helps too: always note the place name exactly as it appears on the station sign, not as it appears in a timetable enquiry. Enquiry systems abbreviate, add extras or normalise characters – the sign on site is the more original source and later matches better with what other collections use.

There’s a side benefit as well: with the correct spelling you’ll find significantly more in forums, image databases and timetable enquiries – and especially the Polish-language sources, which are often the only ones for regional topics. The same goes for company names: search for a company in the Koleje family and you get different result lists with and without diacritics.

Common mix-ups

• ł and l. Two different letters with different pronunciation – and different search results.
• ź and ż. They look similar, but aren’t. The dot and the accent stand for different sounds.
• Pomorskie and Zachodniopomorskie. Two neighbouring voivodeships with similar names – the prefix decides.
• Destination display as proof of company. The text names the destination, not the operator.
• Historical German place names. Useful in old sources, but not the authoritative spelling for current sightings.

Verdict

Anyone who collects sightings in Poland automatically collects spellings too. Learning the nine special characters once takes twenty minutes – and saves a lot of searching in your own collection later. Koleje Pomorskie provides a fitting way in, right there in its company name.
