I booked family tickets first and read the reviews on here afterwards and so I have to say i was instantly regretting having booked without reading the reviews and I was then dreading the journey . In the end I have positive and negative experiences to report . It is most definitely a purely for profit run business that seems to care very little for the paying customer as the seats in the diesel trains are long enough for 3 adults and 1 child and yet they squeeze 5 people in on each side. My family of 4 sat on our bench and we were opposite a family of 3 ( 2 adults and 1 child) when two very overweight people got in with their small child and the family opposite looked horrified (obviously wondering how everyone would fit in ) but had to squash up as the tickets tell you which carriage you are in and so you have no choice as to where you can sit. The small child sat next to me on and off up the mountain as it turned out she was under 3 and so could sit on a parents knee and she didn't actually have a ticket so my family all shoved up as well else there would have been 6 people on that side . You are asked to swap sides on the way back so you can see what you missed , which we duly did , but when the overweight couple went to the opposite side where we had been previously we realised that is the smaller bench of the 2 in the carriage and so only the couple another 1 adult and a small child would fit and everyone else was on my side . 10 people in a carriage is most definitely 2 too many . I hope the company read these reviews and take note. I paid ( with a £3.50 booking fee) almost £105 for our tickets and that's a lot of cash to be squashed to hell . The men serving in the railway cafe were as miserable as it's possible to be and everyone was saying the same thing as they sat outside with their coffees etc. On the plus side the railway is a fantastic , amazing piece of engineering and it was a real treat to go right to the top of a mountain on a train. All the walkers heading up from all directions and so close to the train . The views are super impressive and we know as a family that we will never all walk up Snowdon ( we say we will but i know it'll never happen), so to actually have the privilege of seeing the amazing wild and awe inspiring beauty of the landscape and make it to the summit is a real treat. Half an hour on top if you go up on the diesel but an hour at the summit if you travel on the steam train but that's £35 for a single adult ticket . The steam train carriage looks to have a lot more room inside as well. Some people had missed their train down from the previous trip up and i have to say every effort was made to get them back down on our train which they did , so that's good to know. Half an hour is just enough time to get to the monument right on the top , visit the loo and have a mooch round the shop. So all in all i have to say that the positives outweighed the negatives in our case and we were glad we did it . Just as a final word , we also visited the Electric Mountain Power Station experience 2 minutes down he road and £25 for a family ticket that was indeed excellent value and no booking fee (unlike the mountain railway) either . Don't let the reviews put you off .
