I think the only time you can do the whole thing is on Bank Holiday Mondays, when a M-F service operates and the 09:30 restriction doesn't apply. The few extra peak trains make all the difference, but even then it's on a knife edge and one cock up will scupper the whole thing.
Trust me, it CAN be done on a Saturday as shown below, but it does involve the "cheat" of staying on train from Denby Dale (19.41) to Barnsley(20.06) to pick up the Barnsley (20.33) to Darton (20.38) to continue to Leeds. Extra cost £3.10.
This stage can also be done by "reasonably active" travellers by cycling the 8 miles Denby to Darton in 57 minutes. But we knew we would be 6 pints of real ale in by this point and decided the cheat was worth it!!!!
