Learn Danish: Toget fra Aarhus er forsinket. - The train from Aarhus is late.

In Danish, forsinket specifically means "delayed" and is the required choice for public transport, appointments, or people arriving behind schedule. Sent means "late" in a general time-of-day sense, such as going to bed late (at gå sent i seng) or an event happening late in the year.

Why doesn't the adjective "forsinket" change to match the neuter noun "toget"?

Forsinket is a past participle functioning as an adjective. When a past participle ends in -et, it keeps this exact same form for both en-words and et-words. Therefore, it is both bussen er forsinket and toget er forsinket. However, if the noun were plural, it would take an -e ending: togene er forsinkede.

How is "toget" actually pronounced in natural speech?

The g is completely silent. It is pronounced with a long "o" vowel, a stød (a slight catch in the throat), and the definite -et ending turns into a soft vowel sound. It sounds roughly like "toe-eth" rather than how it is spelled.

What is the difference between saying "er forsinket" and "bliver forsinket" here?

Er forsinket describes the current state of the train, meaning it is currently running behind schedule. If you use bliver forsinket, it focuses on the change of state, meaning the train is getting delayed right now or will become delayed in the near future.
