I was told that Hartland only make trains as a side-line when they have spare production time and their support, design and development is minimal as they are a commercial injection moulding company, rather as Matchbox toys started as a side-line of Lesney. Many of their products are made using 30+ year old Delton and Kalmazoo tooling, so how long they will keep going is anyone's guess, they have already stopped the 0-4-0 locos which I rather liked. They do use good materials though, better than the Chinese made models. I found in the past that hey rarely replied to emails.
