Train A Main Guide: Positions, Angles and How to Clear It

Train A Main is the main Terrorist entrance into the A yard. It runs from the T side and opens almost directly onto Blue train. If you understand Train A Main, you understand half of every A execute on the map. This guide covers what you see when you walk out, where CTs usually stand, and how to clear it without giving away free kills.

If you are new to the map, read our Train callouts guide first. The names below follow the common community set.

Where is Train A Main?

A Main starts near T Connector and Showers on the Terrorist side. It feeds into the A yard, the open area full of parked train cars. The first thing in front of you is Blue train. Olof, a small cubby beside Blue, faces A Main and T Connector. Further in you find Sandwich, the gap between Blue and Green at the top of A.

A Main is not the only way in. Popdog drops Ts into the yard next to E Box, and Ivy reaches A from Alley on the far side. That matters because a lone push through A Main is easy to stop. A push that hits from two directions is much harder.

What angles do you face from A Main?

Train is a map of short, layered angles. Cars block long sightlines, so most fights happen at close range. From A Main you need to think about these spots:

• Olof: a cubby right beside Blue. A CT here can shoot you the moment you step out.
• Sandwich: the gap between Blue and Green. It is a classic off-angle and can catch players who only check the obvious corner.
• Under the cars: CSDB points out that under-car sightlines catch careless players. Feet are visible before bodies.
• E Box: the electric box between Popdog and the A bomb train. CTs use it to watch Popdog, and it can also see players who push deep into the yard.
• Heaven: an elevated position above A reached by ladder. It sees much of the yard and is a common AWP spot.

Do not try to clear all of these at once. Pick an order, pre-aim the closest corner first, and let teammates cover the rest. Our crosshair placement guide explains why pre-aiming close corners saves so many duels.

How to clear A Main as a T

A good A Main hit is about timing and utility, not speed alone. A simple structure looks like this:

1. Gather information. Listen for CTs near Olof or Blue before you commit. A quiet A Main often means the CTs are waiting deeper.
2. Smoke the CT side. CSDB's tips suggest smoking Ivy and the CT lanes so rotators and deep players cannot see the yard.
3. Flash the close angles. A pop flash over Blue helps the first player check Olof. See our pop flash guide for the basic idea.
4. Split with Popdog. Engage from A Main first, then drop Popdog while CTs are looking at Main. Two entry points split their attention.
5. Trade, don't swing alone. The second player should be close enough to trade the entry within a second.

Exact smoke and flash lineups change after updates. Practise them with a lineup tool or a video in a private server rather than trusting a screenshot.

Common T mistakes in A Main

• Walking out wide and getting crossfired from Olof and Sandwich.
• Forgetting to check under the cars.
• Throwing all utility at once, then having nothing for the plant.
• Ignoring Heaven when you plant on the bomb train.

How CTs hold A Main

A CT watching A Main has a delay job. You want to slow the push, get information and survive. You do not need to win a three-versus-one.

• Play close angles early. Olof and Blue can win the first duel, but have an exit ready.
• Use a molotov or incendiary. Fire at the mouth of Main buys time while rotators come through the Z Connector.
• Watch Popdog too. CSDB suggests a molotov on the Popdog ladder and holding the door from Sandwich if you expect drops.
• Reposition after a kill. Ts will pre-aim the spot you just used. Move between cars instead of peeking the same gap twice.

If the site falls, do not force a hopeless hold. Fall back towards the Z Connector or Ivy side and set up a retake with your team. Our Train CT side guide covers the wider setup.

Using A Main after the plant

Once the bomb is down, A Main becomes a safe lane for Ts to play from. Spreading out across the train gaps makes one flash much less effective, as CSDB notes. One player can hold from near Main while others watch Ivy and Z Connector. Learn the bomb and defuse timings in our post-plant guide.

Practice checklist

• Load Train in a private server and walk A Main slowly, checking each angle.
• Stand in Olof and Sandwich as a CT to see what a T sees.
• Test smokes and flashes yourself, because CS2 updates can move cover.
• Review a demo of your own A hits and note where you died.

Sources and checks

Callout names and connections were checked on 1 November 2026 against CSDB's Train map guide, TotalCSGO's Train callouts and the Counter-Strike Wiki page on Train. Train was remade for CS2 on 13 November 2024, and the sources do not agree on every A-site detail since then. CSDB also notes that map geometry can change in updates. Load the map in a private server before you rely on any angle described here.
