Rods_of_Revolution Posted October 14, 2015 Share Posted October 14, 2015 I buy quite a lot of chassis from PlazaJapan on eBay, usually to go under 3D Prints I've designed. I saw recently the Tomytec HM-01 had appeared and I couldn't find much information online, so I bought one (under £20 eBay 351526636630) to see whether it was any good. I thought I'd post my findings here where perhaps they will be of assistance to others modelling N/OO9/H0e. I was amused when I received it this morning as the packaging wasn't what I was expecting! Turns out that it's actually a product aimed at children and it comes with a plastic body and some white decals for them to colour the model in their chosen livery. In the box is a plastic blister pack containing the locomotive, some instructions (in Japanese), the white draw on decals and couple of bags of bits: The locomotive comes with hook and loop couplings fitted as default, but also supplied are standard rapidos (no NEM pocket though.) The main body comes off by flexing the sides outward to release and then lifting it off; contained within the body are some weights. The motor can be separated from the chassis flexing the case outwards at five points and then lifting (a bit tricky!) The plate which is used to hold the body on can be removed and the chassis reassembled without it, to give a narrower profile. The maximum width is 13mm which isn't too bad, though probably a bit wide for most N scale applications. The chassis would certainly work well for OO9/H0e. The chassis also comes with some side plates which are an interference fit; these may be useful as axle boxes and leaf springs could be glued on top. With the weights the chassis was quite happy to pull 4 Mk1s round 9" radius curves. Without the weights it would pull 1 Mk1 without any slipping, though a second Mk1 resulted in slipping on the curves. All wheels pickup power and provide traction, but as the axles slide to the extreme left and right it looks like the wiper comes away from the back face of the wheel, so I bent them inwards until they made more consistent contact. Hopefully this is post is of use to someone! All the best, Jack 4 Link to post Share on other sites More sharing options...
m0rris Posted October 16, 2015 Share Posted October 16, 2015 Thanks for your post. ut of interest, what is the wheelbase for one of these, I presume it is more "small shunter" than EMU bogie sized? Link to post Share on other sites More sharing options...
Rods_of_Revolution Posted October 16, 2015 Author Share Posted October 16, 2015 Thanks for your post. ut of interest, what is the wheelbase for one of these, I presume it is more "small shunter" than EMU bogie sized? The wheel base is 21mm with 6mm diameter wheels, so it's only marginally shorter than a Mk1 bogie. All the best, Jack Link to post Share on other sites More sharing options...
mikeharvey22 Posted October 18, 2015 Share Posted October 18, 2015 Jack The image on Osborns website shows the wheelbase around 16 - 17mm, so still OK for Mk 1 EMUs and first generation DMUs I think. Link to post Share on other sites More sharing options...
jardal Posted July 16, 2018 Share Posted July 16, 2018 Hi folks, I'm new here and it was my Google searches that led me to this specific post. I've recently purchased several of these Tomytec HM-01 chassis and I'm wondering if anyone may have some info regarding how they power them? Rather than risk just plugging in any old power pack/controller, would anyone know what the electrical requirements are for the motors in these chassis?

RMweb Gold chuffinghell Posted August 6, 2018 RMweb Gold Share Posted August 6, 2018 I ran mine using standard 12v DC although I never went above 3/4 on the controller (approx 9v) as it’s a very quick running chassis 1 Link to post Share on other sites More sharing options...
Dieseldog Posted December 28, 2018 Share Posted December 28, 2018 That little shunter looks quite interesting, who is the supplier? I could do with a train like that for my little coal project. Link to post Share on other sites More sharing options...
sparky66 Posted May 28, 2021 Share Posted May 28, 2021 Anyone got any idea if these can still be bought new and where from? I'm looking at Simplex and Ruston bodies on shapeways and they all need these chassis, yet I can't find them anywhere. Link to post Share on other sites More sharing options...
