Plarail Carbon-Dating

There are a number of production and design changes to Plarail that have occurred that can help you to figure out approximately (or even exactly) when a Plarail train or accessory was produced. A page outlining the trends I have identified and use to date the manufacturing of trains can be found here.

Useful Japanese

I have compiled some of the Japanese phrases that I run into and use in conjunction with collecting Plarail here.

Plarail repair information

The repair guides and photos provided here detail some of the methods I use to repair engines and I take no responsibility for any injury to persons or Plarails when attempting to perform any procedure detailed here. Your mileage may vary.

Grain of wheat lights Adding a small "grain of wheat" type bulb to an EF15 locomotive. The same concept can be applied to nearly any Plarail train

3D printable replacement parts

A variety of 3D printable STL files for commonly lost small accessory pieces and the like.

My 3D printer is an Ender 3 Pro purchased in the summer of 2020 and I can not speak to how in-spec it is after several years of use, failed prints, and repairs. Any notes about settings I used are in the file's description.

B/O Tomica/Motor Tomica/Plaroad connecting clip replacement
Replacement clip for the common Tomy road used in the 90s and 2000s. Over time the clip that catches on the protrusion of the connecting road can snap off. This drop-in replacement clip provides a decent grip, even when used on both halves of a road joint. The clip is slightly oversized and is meant to be filed down after printing to fit a particular joint. They are a little bit loose of a friction fit inside the original plastic molding around the joint and should probably be glued in place for long term use.

I printed my test pieces at the default "standard quality" settings in Creality Slicer 3.8 and then did the final prints in "super quality." The print time was about four minutes at standard and nine minutes at super.

DD51 body shell clip replacement Small replacement clip that should fit all variants of the DD51 with clip-on shell. Sand down the thinnest portion of the clip on the "top" side and apply glue on the same area and then hold it all the way forward in the protruded portion of the molding inside the DD51 shell in the same position as the original clips. I printed these at "Super Quality" with 10% infill but I think they would come out ok at lower settings, especially if you sand down any rough corners.

I use cheap paint pens to color white prints to match the body shell it is attached to after gluing (I have only ever bought white 3D printer filament).
EF15 body shell clip replacement

v2 - left | right
v3 - left | right
Small replacement clips for the EF15 top shell. There is a "right" and "left" clip as the protrusion that is glued to the body must fit around internal supports inside the shell. This internal reinforcement seems to leave a small portion of the original clip hanging down in some cases - v2 of the clip sits right against the body shell while v3 fits below the small reinforced stub. A "left" v3 clip is shown installed to the right, as well as both the left and right clips.

Like the DD51 clip, sand down at least the "top" side of the thinnest portion of the print and then glue it into the case in the same position as the original clip, with the extended support tongue nestling it between the protrusions in the molding also providing support.
"Long" Tomy coupling Longer style rear loop coupling used on older D51s, DD51s, and some other engines with longer chassis. I do not believe Tomy sold these as replacement parts. I print these with supports to have the coupling end be thicker on both sides like the original and then sand the supports away.
Mickey Poppo battery cover Battery/tender cover for old-power Mickey Poppos. Should also work with new power types, but might need the "clips" extended downwards like the original new power Mickey Poppo variant. Unlike the small body clips, I don't think the paint pen method looks particularly good here. The proper way to make these would probably be out of a color-matching filament with plenty of sanding down for smoothness, although some of the recesses can be hard to get into.
Amusement park train parts A number of pieces to replace broken components of the Child Guidance/Amusement Park trains. Pieces work best printed in high quality and do not take that long to print (the longest take about 20 minutes).

The front contact holder can be glued into the front of the chassis and holds the front battery contact.
The bottom bracket clip can be glued to the chassis and replaces the original clip that holds the activation tab bracket onto the bottom of the train.
The rear contact holder is also glued into the chassis and holds the rear battery contact in place.
The wheel clips replace two broken tabs on the gearbox carrier plate that are sometimes broken and prevent the rear wheels from sitting in the gearbox correctly.
The rear screw post replacement piece can be glued in to the back of the chassis if the original screw post is broken. The original post needs to be cut away and filed down.
More details are available on the Amusement Park train repairs page.
Amusement park stop track parts

20mm spacer
10 tooth gear
20mm long spacer and ten tooth gear for use on Child Guidance and Plarail amusement park series stop rails. The original ten tooth gear commonly splits and can fall off along with the plastic spacer over time.

Although I do not usually like printing gears, the shafts these gears ride on are 3mm in diameter instead of the typical 2mm and the gears are in simple and already loose gearings and can just about be managed by my printer. With a little cleaning up after printing at high quality I would describe them as working in a pinch.
Ticket Play Station cards and tickets

Orange card
Ticket
Replacement tickets for the Plarail Ticket Play Station which was first released in the 1993 Doll Play Ticket Play Station Set and later individually.

The larger "orange card" prepaid train cards fit into the upper slot and pressing the red lever dispenses a ticket from a stack of up to six.

You don't really need to 3D print these, you could just as easily cut down any decently rigid material, it was just easy to throw the dimensions into Tinkercad without having to find or cut down a suitable material. I printed mine in the "low quality" preset with 10% infill. Eventually I would like to either scan or potentially recreate the ticket design and make proper replacements with appropriate graphics and coloration, but it may be easier to just find a used but complete copy of the station
