El trayecto en tren hasta la capital cuesta sesenta euros si compras los billetes hoy.

Both can often be translated as trip or journey, but they are not always used in exactly the same way.

• el trayecto usually refers to the route, journey segment, or the act of going from one place to another
• el viaje is broader and often means trip in a more general sense, especially when talking about travel as an event

In this sentence, el trayecto en tren hasta la capital focuses on the specific train journey to the capital, so trayecto sounds very natural.

In Spanish, en + means of transport is the normal way to say by a vehicle:

• en tren = by train
• en coche = by car
• en autobús = by bus
• en avión = by plane

So el trayecto en tren means the journey by train.

De tren would not work here with this meaning.

Hasta means up to, as far as, or until, depending on context.

Here, hasta la capital means to the capital in the sense of destination:

• el trayecto ... hasta la capital = the journey ... to the capital

Spanish often uses hasta when talking about the endpoint of movement. It emphasizes the destination as the limit or final point of the route.

La capital means the capital city. Spanish often uses this kind of noun phrase when the context makes it clear which city is meant.

So instead of saying Madrid or another city name, the sentence uses la capital as a general reference.

This is completely natural in Spanish if the listener already knows what capital is being discussed.

Because the subject is singular: El trayecto en tren hasta la capital.

The verb costar agrees with the thing that costs money.

• El trayecto ... cuesta = The journey costs
• Los trayectos ... cuestan = The journeys cost

Even though sesenta euros is plural, that is the amount being paid, not the grammatical subject.

Spanish numbers do not change for plural in this way.

• sesenta = sixty
• treinta = thirty
• cuarenta = forty

They stay the same before a noun:

• sesenta euros
• treinta minutos
• cuarenta personas

So sesenta euros is correct.

Spanish often uses the present tense after si when talking about a real possible condition in the future.

• si compras los billetes hoy = if you buy the tickets today

This structure is very common:

• Si vienes mañana, te lo doy.
• Si estudias, apruebas.

In English we also often use the present after if: If you buy the tickets today...

So this is a normal real condition pattern:

• si + present
• main clause often in present or future-like meaning

Because this is not a subjunctive trigger.

With si meaning if, Spanish normally uses:

• present indicative for real or likely conditions
• not the subjunctive

So:

• si compras los billetes hoy = correct
• si compres los billetes hoy = incorrect

The subjunctive does appear in some more hypothetical or literary structures, but not in this standard everyday type of sentence.

Because billetes means tickets, and Spanish often uses the plural where English might use either singular or plural depending on context.

If you are buying train tickets for a journey, Spanish commonly says:

• comprar los billetes

Even if English might sometimes say buy the ticket(s), Spanish often uses the plural naturally in transport contexts, especially when referring to travel tickets in a general sense.

Also, billete in Spain is the normal word for a train ticket, bus ticket, etc.

This is a very common question.

In Spain:

• billete = a ticket for transport, such as train, bus, plane
• entrada = a ticket for entry, such as cinema, concert, museum, football match

So here, since it is a train journey, billetes is the right word.

Examples:

• billete de tren = train ticket
• entrada para el cine = cinema ticket

Both are possible, but the word order changes emphasis.

• si compras los billetes hoy = neutral, natural
• si hoy compras los billetes = more emphasis on today

Spanish word order is more flexible than English, but the version in the sentence sounds most natural in ordinary conversation.

Yes. The verb costar has two common meanings:

1. to cost

   • Cuesta sesenta euros.
   • It costs sixty euros.

2. to be difficult / to take effort

   • Me cuesta madrugar.
   • It’s hard for me to wake up early.

In your sentence, because of sesenta euros, the meaning is clearly to cost.

Yes, in many situations you could.

• cuesta sesenta euros = costs sixty euros
• vale sesenta euros = is worth / costs sixty euros

For prices, both are common.
However:

• costar focuses more directly on the price
• valer is also very common in everyday speech for saying how much something costs

So El trayecto ... vale sesenta euros would also sound natural.

Because after costar, the price normally appears directly, without an article:

• cuesta sesenta euros
• cuesta diez euros
• cuesta mucho dinero

You would not usually say cuesta los sesenta euros here.

Spanish treats the amount as the complement of the verb, not as something needing an article in this structure.

A very natural everyday alternative might be:

• El viaje en tren a la capital cuesta sesenta euros si compras los billetes hoy.

Or even:

• Ir en tren a la capital cuesta sesenta euros si compras los billetes hoy.

These versions are not necessarily better, just slightly different in style.

• trayecto sounds a bit more specific or formal
• viaje is broader and very common
• ir en tren is simple and conversational

Yes, it leans toward Spain usage.

In Spain, billete is the standard word for a transport ticket.
In much of Latin America, people may also use:

• boleto
• pasaje or pasillo? no, not pasillo
• pasaje in some regions for fare/ticket

So billetes is perfectly standard Spanish, but it especially matches Spain Spanish, as your prompt suggests.

Yes, very naturally.

The sentence suggests that the price is sixty euros on the condition that you buy the tickets today. This often implies:

• a discount
• a time-limited price
• an advance-purchase fare

So grammatically it is just a condition, but pragmatically it can sound like a special deal.

A rough pronunciation guide is:

el tra-YEC-to en tren AS-ta la ca-pi-TAL CUES-ta se-SEN-ta EU-ros si COM-pras los bi-LYE-tes OY

A few useful notes:

• trayecto: the y sound is like English y in many accents
• hasta: the h is silent
• capital: stress on the last syllable, -tal
• cuesta: pronounced roughly KWE-sta
• billetes: in Spain, ll may sound like y; in some areas it may sound slightly different
• hoy: sounds like oy

In Spain Spanish, the rhythm would be smooth, with the main stress points on: trayecto, tren, capital, cuesta, sesenta, compras, billetes, hoy
