Having only recntly started the hobby myself after getting a Blue rapier set for christmas, im still slowly building the layout, track is down and have planned out where stations etc are going. I have two young children so days off are 90% spent as family time but i do get a few hours to do stuff on my layout. Everytime I get on the layout i always think to myself is that all ive done the last few months. But also think its not to be rushed. It is very addictive and I've spent a fair bit already on things, locos (pre owned but both have started running awful and oil hasn't helped so will save for new in future) carriages etc, track and so on, also a few cars and buildings etc. Not to mention a newer better controller (gaugemaster ) I don't really drink much and don't smoke and my main hobbies are train and plane spotting which is basically free (free or discounted rail travel) and just fuel to drive to airport locations. Its a good thing to of gotten into in my opinion and it helps me focus and forget about all the negativity in the world currently i just focus on my railway. I've worked out I've spent a good £500-600 or more so far on things. Biggest regret is buying pre owned locos via a auction site and finding out after a few hours running they are now running awful. And as many say its your layout your railway so do as you please. Run what trains you like. And enjoy
