Baku central railway station has gone through some serious modernization recently.
We booked a train to Baku from Tbilisi in early August 2019, and that's how I first visited this railway station.

According to RailwayPro - It took 2 years to renovate and modernize the whole capital’s rail station. The station has a shopping area on the second floor, the main building has been renovated and all the platforms been reconstructed.
Baku Railway building
Inside the building, there are modern facilities - a shopping and dining area (a hint at Pizza hut they have a free Wi-FI). There is a few ATM located inside the building, I was able to withdraw 95 manats here from VISA card (the commission though was about 3 EUR)

On the left there is a RVR train departing/arriving.
Rīgas Vagonbūves Rūpnīca (RVR) is one of the largest machine-building plants in Latvia, founded in 1895 by the businessman Oscar Freywirth under the name Phoenix. RVR is based in Riga and was for many years the largest producer of electric and diesel trains and also tramcars in the former Soviet Union.
We took a street taxi from here to get to the boulevard for about 8 manats (It's a way too much, and I would recommend using Bolt app for hiring a taxi, see: How to Get around in Baku by using Taxi Mobile Application Bolt
It was planned that we will return to Tbilisi from this station, but we were not able to buy return tickets for our dates, and instead, we fled back with Buta airways, see: About Buta Airways Baku - Tbilisi fight
