Le train est supprimé à cause de la panne.

That is a very common question. In French, supprimer has a broader range than English suppress.

In transport and scheduling contexts, supprimer often means:

• to cancel
• to remove from service
• to withdraw

So:

• Le train est supprimé = The train is cancelled

You will also see this with other services:

• Le vol est supprimé = The flight is cancelled
• Le bus est supprimé = The bus is cancelled

So even though supprimer can mean delete/remove, in this kind of sentence it is best understood as cancel.

Because this sentence uses the passive voice.

• supprimer = the infinitive, to cancel
• supprimé = the past participle, cancelled
• est supprimé = is cancelled

Structure:

• Le train = subject
• est = form of être
• supprimé = past participle

So literally, this is:

• The train is cancelled

Compare:

• La compagnie supprime le train. = The company cancels the train.
  
  • active voice
• Le train est supprimé. = The train is cancelled.
  
  • passive voice

Because it is the past participle of supprimer.

For regular -er verbs, the past participle usually ends in -é:

• parler → parlé
• annuler → annulé
• supprimer → supprimé

In est supprimé, the participle works like part of a passive construction: is cancelled.

Also, it agrees with the noun it describes when used with être in the passive:

• Le train est supprimé (masculine singular)
• La ligne est supprimée (feminine singular)
• Les trains sont supprimés (masculine plural)
• Les lignes sont supprimées (feminine plural)

Both can express a reason, but they are used differently.

à cause de

This is followed by a noun or noun phrase.

• à cause de la panne = because of the breakdown

parce que

This is followed by a full clause with a verb.

• parce qu'il y a une panne = because there is a breakdown

So in your sentence, la panne is a noun phrase, which is why à cause de is natural.

Compare:

• Le train est supprimé à cause de la panne.
• Le train est supprimé parce qu'il y a une panne.

Both are possible, but the grammar after them is different.

Panne usually means a breakdown, failure, or malfunction.

In transport contexts, it can refer to:

• a mechanical failure
• an electrical failure
• a system problem

So à cause de la panne means something like:

• because of the breakdown
• due to the fault
• because of the malfunction

It does not usually mean a flat tire here or a minor issue; in railway announcements it often refers to some technical problem affecting service.

Because panne is a countable noun here, and in French you normally need an article.

• la panne = the breakdown
• de la panne = because of the breakdown

The expression is à cause de + noun, but de combines with the article that belongs to the noun:

• à cause du retard = because of the delay
  (de + le = du)
• à cause de la panne = because of the breakdown
• à cause des grèves = because of the strikes
  (de + les = des)

So the la is there because panne is feminine singular and needs its article.

Because panne is a feminine noun: une panne.

That is why you get:

• la panne = the breakdown

Unfortunately, grammatical gender usually has to be learned with the noun. A good habit is to memorize nouns with their article:

• une panne
• un train

Then it becomes easier to build phrases correctly:

• à cause de la panne
• le train

Yes, absolutely. Annulé is also very common and often translates directly as cancelled.

So both of these can work:

• Le train est supprimé
• Le train est annulé

There can be slight usage differences depending on context, company style, or transport announcements. In public transport, supprimé is especially common for a train, stop, or service that has been removed from the schedule or is not running.

For a learner, it is useful to know:

• annuler / annulé = cancel / cancelled
• supprimer / supprimé = remove, cancel, withdraw from service

Yes. Grammatically, est supprimé is in the present tense of être, but in meaning it often describes the train’s current status:

• The train is cancelled

This is very normal in announcements and notices. French often uses the present for current official information.

So it is not really about a past action in the storytelling sense; it is giving the train’s present situation.

A careful pronunciation would be approximately:

Le train est supprimé à cause de la panne
luh trẽ eh sy-pree-may ah koz duh lah pahn

A few useful notes:

• train has a nasal vowel, roughly like trẽ
• est is pronounced eh
• supprimé stresses the final sound group in natural French rhythm
• à cause de sounds like ah koz duh
• panne sounds like pahn

In connected speech, French flows smoothly, so try to say it as one group rather than word by word.

You could translate it literally word for word, but it would sound wrong in English.

This is a good example of a false friend:

• French supprimer does not always match English suppress

In this context, the natural English translation is:

• The train is cancelled because of the breakdown.

So when learning French, it is better to think of supprimer here as cancel/remove from service, not suppress.
