    Yep... those were released a few months ago. San Jacinto and Buffalo Bayou together... then Rampart Range more recently.

    I'm guessing you got the first two coaches Mistletoe and Waterloo about a year ago.

    BTW... it seems you got caught up in the same logistical foul up that happened to me in early 2022. Lowell had to verify what was sent or not... I ended up getting 9 cars under one shipment. It was like Christmas in February... LOL.

    Sure wish those were DCC compatible!

    As a fan of obscure motive power and a glutton for punishment, I couldn't resist picking up an old Minitrix FM H-12-44. If it's anything like the Minitrix F-units, it'll be worth the pain of bringing up to modern spec.

    can a decoder not be hardwired into these? I have several and was my plan...

    As long as you have the room which wouldn't require much if using something like a lokpilot micro, Lenz LE077XF or Zimo mx616.

    I've wired up locos that make those relatively spacious with regards to room for a decoder. Would be a quick job. Could even add interior lighting and why not with everything apart?

    Because of the coreless motor they use in them, it’s not recommended.

    Unfortunately those do not come powered… fortunately they are easy to add power.

    See https://dccwiki.com/Coreless_Motor

    This subject is controversial, but the link provides some useful information and guidance.

    Among them are that the decoder's motor output PWM frequency should be > 20KHz, and you should NOT use DCC zero-stretching mode (via address zero) to drive these as DC locos from DCC.

    The bulk of the problem with using these motors with DCC is that since there is no feromagnetic core for the windings, they have very little inductance. This means that a zero voltage PWM output (still with lots of AC voltage) will cause excessive current and overheating, melting the core winding insulation and bricking the motor. There are some PWM waveforms that do not emit AC at zero DC voltage exist, but it is less efficient, and small decoders are unlikely to use them. Even then, operating the locomotives at very low speed (so the armature cannot generate enough airflow to cool itself) is not advised.

    Fortunately, some modern, miniature DCC decoders operate at high PWM frequencies, and may be suitable for use with coreless motors in locomotives.

    Note, some DC power packs may use unfiltered PWM at fairly low frequencies, and may not be suitable for these locos as well. Adding capacitive and/or inductive filtering on the output would help.

    If I were going to try these, I would probably buy one, install a high frequency PWM decoder, and try it out, before I invested in a fleet of them.

    I forgot to mention that the articulated power chassis was ordered along with some parts to make it diesel powered.

    There several shells for this so you can get different looks.

    Great information there. Thanks! I know the V5 lokpilots allow for up to 50Khz and even have a "coreless-small diameter" motor pre-set if you use their lokprogrammer and software.

    Yes it is. I got a set like that several years ago at a show for $60.00 and was really happy with that price. It's also a great running set.

    Congrats ! Any of the brands of containers will work with that set. Containers are so over priced these days so shop carefully. Saw lots of bargains today at a club open house but did not buy any as I had filled my need for containers from their previous open houses.

    Is that even possible, to "fill one's need" for containers?! How did you do that?!

    I just print my own, they are too expensive to buy commercially made.
