The trains 4438XX and 4439XX are both odd, so it could be confusing (for example) train 443835 goes to Dabrowa Gornicza while 443935 goes to Myszkow, but both trains are on same side in the EDR.
Yesterday I had a delayed train 4438XX in Zawiercie GT (left side), so I thought first, it would be the train 4439XX heading to Myszkow...
