I have just started on the O14 NG part of a7mm scale lime works and quarry with a standard gauge main line transfer facility.I had earlier purchased and built a Nonneminstre kit for an O&K locomotive that comes complete with chassis, wheels and motor, plus some KB scale skip wagons. there seems to be a very small number of industrial petrol or diesel locomotoves avaialble for O14 except those from Nonnemistre that need a Wrigthlines chassis which is no longer generally avialable.

There is of course the very nice plate-frame Simplex from Nigel Lawton but I am afraid this would be beyond my modelling skills to build. I am after some typical industrial/quarry type locomotives such as Simplex, Hudson Hunslet and Ruston. Is there anything out there with an easily built or ready-to-run chassis?

I have used Tenshodo chassis before but have not found them to be very good at tight curves or slow running.
