Containers

Shipping containers became a popular means to ship goods in the sixties, and have only become more popular since. British Rail introduced its own variant, Freightliner, in the mid-sixties, pioneered by Dr Beeching, better known for closing railways. It was originally envisaged as a domestic solution, however it was international trade where is took off.

An international standard, ISO-668, appeared in 1968, based at least in part on the UK standard, though not quite identical to it, and this slowly replaced the UK version.

Early international shipping containers were a variety of designs, but all the same width and height, and either 20', 30' or 40' long. Today the design has standardised on the corrugated sides, and 30' containers are rare, but there is some variation in height - which is a problem in the UK as many routes are not suitable for the higher containers.

The old UK shipping contains seem to have varied rather more, including 10' containers and 27' containers (lorries were limited to 27').

I have created a  number of styles, which I have given my own names to.

Corrugated

As far as I can tell, all modern containers are this style, but it is not out of place in the seventies either. I did 20', 30' and 40' versions, a dozen in total.


By about 1990 (or earlier?), 30' containers had become rare.

These two are open. the doors are so thin they are translucent. They were printed separately, and glued on.




Vertical ribbed

A lot of old containers were this style.



Smooth ends 

As corrugated, but the last two ribs are missing at either end of each side. This was often used for a logo.



Horizontal ribbbed 

A lot of freightliner were this style.


Chemical containers

At the back are three "tanktainers", and in front a multiple element gas container (MEGC), also known as a tube trailer.


Tanktainers are used for both gases and liquids, and possibly dry powders too. They have been around since the late sixties, originally under the trade name Isotank. I suspect they were fairly rare, despite originating in the UK.

One flow that was around back then was Guiness from Ireland. Here then is a Guiness tanktainer. I am not sure if this was the right style for that era.





MEGCs are more recent, possibly from around 2017, though the legislation seems to be from 2004. This version has two rows of five cylinders, but they seem to go up to three rows, with one less cylinder on the top row. There are used exclusively for gases, and can take much higher pressures (up to 180 bar or even 250 bar). For a compressed gas (as opposed to a liquified gas), that means you can put much more in.

Ordinary containers are used for liquids too, the liquid being contained in a bag. I would not be surprised if this was limited to non-hazardous liquids. Australian wine is one example.

Introduction to the Blog

 My first post was back in February - before I had even purchased a 3d printer, and it is now November and I am writing the introduction... This blog is all about my experiences for 3d printing. It is a way for me to share what I learn along the way, and to show off what I have created. Most pages are tagged Model and are about a specific model, and the prototype it is based on. Generally I try to visit the prototype, and include a couple of photos of that for comparison. I also try to learn the history of the building, which is not always easy, and record that on the page too. A lot are buildings in and around Preston, as that is where I live. Models are further divided into Building , Railway (i.e., railway-related buildings), Feature (bridges, tunnel portals, etc.), Rolling Stock , Vehicle and Clutter (smaller items) In addition, there are pages tagged How to and Prototype . If you want to know how to use Blender to make 3d models, there is an article I wrote on another s...

Various tank wagons

Image
I am a chemist by profession, and so the transport of chemicals by rail is of interest. In fact I wrote an article on the topic, see here . Nitrogen Liquors The appeal for these is in the name, which makes no sense at all if you are a chemist. They actually contained ammonium nitrate, which is a fertiliser used to put nitrogen in soil, which will be where the name comes from, presumably a solution in water, that is likely both hot - given the wagons are lagged - and very concentrated. Images of the prototype can he found here . They are so dirty it is not possible to tell the original colour, but I am guessing green? One end has four flanges; these would have been to allow the contents to be heated using steam. They were printed separately. The wagons have channels down the sides to catch spills. i guess this is to ensure the solution down not end up between the rails, where it could mix with oil to create an explosive mixture. The ladders are brass. The chasses are Peco. Carbon Dioxid...

Safety First!

 They are hazards associated with resin 3d printing, and you should be aware of them and act appropriately. What do I know about it? I have worked in the chemical industry for several decades, part of my job is writing safety data sheets and I currently serve on a committee reviewed safety across an entire chemical plant. That said, I am not an expert on resin, so this is only a guide. You are the one who is ultimately responsible for your safety! iso-Propyl Alcohol (IPA) IPA is harmful and flammable. Keep it away from naked flames and electrical sparks. That said, with a flash point of 12°C, it is safer than acetone (-18°C) or petrol (-43°C). Do not drink it. Yes, it has alcohol in the name, but it would still be bad for you. Try to keep it off your skin, but it is not that big a deal. IPA was the main ingredient in the hand wash we were all deliberately putting on our hands during "lockdown", so it is really not that hazardous. If you have a reaction to IPA, it is more like...
