Clear train callouts are vital because Train's A site is a yard full of rail cars that look alike. Saying "behind the train" is useless. Saying "one Green, one Sandwich" tells your team exactly where to look.
A quick note on status. Valve removed Train from the Active Duty pool when Premier Season 4 began in January 2026, and it had not returned when we checked on 1 November 2026. You will not see it in Premier for now. You can still load it offline, and it may be available in other modes, so check the in-game map list. If Valve brings it back, these names will still apply.
How is Train laid out?
Terrorists spawn on one side of the yard. For A, they can push through Main, take the outer lane called Ivy, or go through Popdog, the small ladder room that links the halls to A. For B, they go through the halls and choose Upper B or Lower B. Counter-Terrorists spawn near both sites, and Z Connector links CT spawn to B.

A site callouts on Train
- Main: the main T entrance into the A yard.
- Ivy: the long outer lane on the A approach. CTs often watch it from a distance.
- Popdog: the small ladder room between the halls and A. CTs often contest it early.
- Blue, Green and Red: the coloured rail cars that split the site. Use the colour every time.
- Bomb Train: the rail car the bomb is usually planted beside.
- Sandwich: the cramped gap between the trains that CTs use for cover.
- Olof: a corner on A named after a famous boost spot, often hit with a Molotov.
- E Box: the electrical box near the A trains.
- Heaven and Hell: the raised CT sniping spot over A, and the lower area under it.
- Old Bomb: an older plant spot on the A side that players still name.
B site callouts on Train
- Upper B: the raised hall approach with better vision for Ts.
- Lower B and Ramp: the lower tunnel route near the ramp, which is riskier to push.
- Oil: the oil tanker on B.
- Spools: the round cable spools used as cover near the plant area.
- Headshot: a strong head-height angle inside B.
- Catwalk: the raised walkway near the B halls.
- Z Connector: the CT link between spawn and B. Most teams shorten it to Z.
Why are colour calls so important on Train?
From inside the A yard, the rail cars block most sightlines. If you call a colour and a side, such as "behind Red, CT side", a teammate across the site can pre-aim the right gap. If you only say "on site", they have to clear every car.
Smokes and flashes over the trains decide many A hits. Learn the basics in the utility basics guide. When you play without a team, the CS2 solo queue guide explains how to keep calls short with strangers.
How can you still practise Train?
- Start an offline match or a private match on Train and walk every route.
- Learn Main, Ivy, Popdog and the train colours first.
- Then add Heaven, Hell, Upper, Lower and Z Connector.
Overpass also left Active Duty in 2026, and its names are covered in the Overpass callouts guide.
Sources and checks
Callout names in this guide were checked on 1 November 2026 against the TotalCSGO Train callouts list and against common usage in CS2 team comms. Names were also compared with the Tradeit Train callout list (May 2026). Map pool status was checked against esports.gg's Season 4 report. Teams often add their own nicknames, so agree on names with your group before a match.
Frequently asked questions
Is Train in the CS2 map pool?
Train left the Active Duty pool when Premier Season 4 started in January 2026. It had not returned when we checked on 1 November 2026, but you can still play it offline.
What is Popdog on Train?
Popdog is the small ladder room that links the T halls to A site. Both teams often fight over it early in the round.
Why are the trains called by colour?
The rail cars on A look similar and block sightlines. Calling Blue, Green or Red tells teammates exactly which car an enemy is behind.
