They do have a ballast tamper, as there is also classic ballasted track in some tree lined boulevard kind of sections. They have sleepered track left only in depots.
Tampere will use concrete sleepers in some roadside exclusive right of way sections, but even then every stop has reinforced slab with rheda style sleepers, because the torance between the stop and the door is something ridiculous like 3 cm. Helsinki has 10. It has been suggested to simply reduce the tolerance to 5 cm to allow 240 cm wide cars all the way down, now the Artics are slightly narrower at stop height.
Lund method is different as it seems to have pre-fabricated reinforcements embedded into the slab. As I have understood, the traditional method doesn't use reinforcements but correct me if I'm wrong. Hence it's nickname "concrete cake". It has two pours of concrete though and I don't know their exact purpose.
