From doing this on a regular basis, walking from the Luas to Heuston (at a good pace not a saunter) and vice versa (it is slightly quicker to Heuston as it is downhill - you do notice!) it takes me between 25 and 35 minutes depending on traffic and how late I am
The fastest way is to cut across from the Sandyford end of the stop at the Green via York Street, down Peter Lane, onto Golden Lane to Bull Alley, across Patrick Street into John Dillon Street, onto Lamb Alley, down High Street to the quays and then along to Heuston. I usually take Thomas street and go down Steeven's Lane though as there is less crossing of traffic and it is a bit quieter. It wouldn't be a route I'd be happy doing late at night on my own but it is grand during the day and you don't have to dodge too much with traffic since much of the route will be relatively quiet (other than crossing Aungier St, Patrick St and Thomas St)
flahers you wuss During the day it is as safe as walking through any area of Dublin. At night it may be a bit less safe than some other parts but it isn't quite as bad as Skid Row (I decided best NOT to walk down there )
I was counting on getting the 92 bus tomorrow from Heuston Station to St. Stephen's Green. Just checked and found this bus no longer runs. There doesn't seem to be any alternative. Am I wrong?
The 145 is very frequent but occasionally there can be problems getting on it as it brings passengers in from Kilmacanogue and UCD to the city, so getting on on Dawson Street (where a lot of them get off) or Suffolk Street might be easier than at the Green.
