running and commuting buggy- out & about nipper sport?

[Frowndalier]

Looking for advice on whether this is achievable with the out n about nipper sport, or indeed any running buggy! Hoping to get back into running to work with 10mo dd. Will be taking a very early (so not packed) train for 15 mins then running along roads about 5 miles to work where dd's nursery is. Ample buggy storage at that end and taking an early train back. From my research and looking at previous threads i think the out n about nipper sport will be best due to its low weight. The slightly fiddly fold and lack of swivel option for wheel make me a tiny bit worried in case of train problems but i guess I'd be no more bulky than people who take bikes on! Any more suitable alternatives anyone can recommend?
