Just some food for thought on 0-6-0 Docksiders...Lionel has several new Lion Chief Plus 2.0 Docksiders somewhere in the pipeline. They were due sometime late summer/early fall I thought. Haven't checked the shipping schedule lately.
Anyway, these appear to be feature rich at a decent price. Dave Olson mentioned (in a thread several months back) redesigned electro-couplers, smoke units, etc. I've got one on pre-order.
EDIT: Just an addition to say that according to the latest Shipping Schedule these 0-6-0's are showing a November 2020 delivery. So appears that have slipped once again.
