The Eiger Trail is rated medium as for technique and required physical fitness. The trail between Eigergletscher station and Alpiglen station is 6 km. long and can be done in about 1h 50. If you only want to walk a small part of the trail, I guess it can be done on running shoes if wheather conditions are good. However, I wouldn't recommend it (better safe than sorry): you are quite high up in the mountains there and will follow a rocky path. By the way: a (Google) search for "Eiger Trail" will give you lots of information.
If hiking boots are not an option, you might consider walking part of the hike Kleine Scheidegg to Männlichen.
Trains run rather frequently between Grindelwald and Kleine Scheidegg. The timetable
will show you all the details. There's no need to make reservations.
Enjoy your month in Europe and especially the Jungfrau region!
