Ets 0-4-4-0. Available now
Ets sequoia 2-4-4-0, available in April
These are tinplate based locomotives, made from ETS's modular parts. The Sequoia is loosely based on an American logging prototype.
You could argue that a Garratt locomotive would have been better for logging.
ETS also makes a 2-6-0+0-6-2 in a couple different paint schemes that are available with a two week lead time.
Before his passing Porta drove the manufacture of two small Garratt locomotives that are working steep and twisty rails in Argentina. These would be fun models as well.
