Hello, my name’s Rose and I’m a student at University College London, where I’m studying for an MA in Digital Humanities. As part of my course I spent ten weeks completing a placement at the BPMA, working with Martin, the Head of Digital, and Rachel, the Digital Media Manager.
One of the main projects I worked on involved creating 3D models of items from the museum collections using photogrammetry, which I wrote about previously. I’d already learnt a little about the techniques involved, and this project gave me some valuable practical experience putting those lessons into action. It was amazing to be given access to photographic equipment and modelling software, and to have the freedom to experiment with different techniques. I benefitted a lot from the Digital Team’s photography knowledge, and I’m very proud of the models our experiments produced! Check them out here: https://sketchfab.com/postal
Another project involved digitisation work of a different kind, scanning historical maps and documents. A highlight was handling documents related to the sinking of the Titanic, and learning about the Post Office and Mail Room which were on board. This really made me appreciate how unique a resource the BPMA’s collections are.
I also digitised the negatives of maps depicting different postal routes; it was fun to take a small piece of film and digitise it to reveal the detailed and colourful illustrations it held. Digitisation can help preserve the museum and archive collections and make them more accessible; it’s exciting to think these images could help engage people in the story of Britain’s social and communications history.

I really enjoyed my time at the BPMA as I was given the opportunity to develop so many new skills and to work on more projects than I have space to mention! I’m interested in seeing how digital technologies continue to play a part in the BPMA’s work, and especially in the new Postal Museum. My placement gave me a valuable insight into life in the museums and heritage sector, and I’m extremely grateful to everyone I met who took the time to talk to me about their role.

Imagine a place frozen in time, left exactly as it was the day that everyone left it. That is what it’s like in Mail Rail today. After it was mothballed in 2003, everything was left as it was that day, down to the newspapers, rota and personal belongings. This time capsule effect is part of what makes Mail Rail unique and exciting; however when we start construction later this year to convert it into a ride and visitor attraction we’ll have to make a few changes to ensure it’s safe and accessible for visitors. We are keen that the space remains as true to how it is now as possible, but these changes mean that the little things could be lost. We thought long and hard about how we could preserve Mail Rail exactly as it is today. The solution we came up with was 3D scanning.
Just before Christmas ScanLAB Projects, a 3D scanning and visualisation company based in East London, spent a week down in Mail Rail and captured the Mount Pleasant depot, loop and platforms in 3D. In total they completed over 223 terrestrial laser scans with incredible and accurate results.

The scans that ScanLAB have created show all the minute detail of the spaces, preserving Mail Rail as it is now for us all to explore in years to come, including parts of Mail Rail that visitors to the site won’t be able to see, such as the train graveyard.

Of course the results have got our creative gears spinning. Increasingly visitors are expecting an increased level of digital interactivity from a visitor to a museum, allowing them to interact with exhibits and collections through devices such as smart phones and tablets, before, during and after their visit – but how can we use these scans to enhance the visitor experience, both physically and remotely?
The guys at ScanLAB gave us a demo of just this; using an Oculus Rift headset we explored the train graveyard and the depot. BPMA staff delighted in walking around, reaching out to touch trains and walls, and even ‘sitting’ in one of the trains!

Other possibilities include augmented reality apps for smart devices, projections or 3D printed installations –the options are endless– so what would you do with them?

Last week was an exciting one for the Digital team here at BPMA! For the past five days, Rachel and I have been accompanying ScanLAB Projects Ltd. while they undertake a 3D survey of Mail Rail.

ScanLAB have been targeting the areas of the network that are to be the focus of our Mail Rail visitor attraction – that is the work depot at Mount Pleasant, the platforms beneath Mount Pleasant and the tunnel loop from the depot to the platforms – just about 1km of tunnels.
Will from Scanlab discusses the technology with guests from FARO, New Scientist and Harry (BPMA Communications Manager).
The 3D scanning of Mail Rail is important in that it captures the industrial heritage of an unexplored and little-known feature of central London. The survey records the details and the features of Mail Rail as a working space, with all the flotsam and jetsam left behind when the service was suspended. From tools and equipment to newspapers and calendars from over a decade ago, Mail Rail is a time capsule just waiting to be explored. These features will inevitably be tidied up when we open it to the public so it is crucial to capture that detail for posterity.

The survey will allow users to see these features in three dimensions – bringing the platforms to life in ways not possible even when the train ride is running. The survey can be shown via the web and used in the exhibitions we create at the Postal Museum and Mail Rail attraction to offer a truly explorative experience of Mail Rail in a way that the train ride cannot. Imagine navigating the tunnels and platforms for yourself?

Using the latest scanning technology from FARO, and using the surveying and imaging expertise of ScanLAB, we will be obtaining as faithful a representation of the site as we possibly can. From the work depot to the platforms and the tunnels in the loop around Mount Pleasant, we will be recording a truly significant piece of Britain’s industrial history.

It’s been an exciting month for those involved in our 3D digitisation project, as it moved into the trial stages. A while back we shared what objects we selected for the scanning. A couple of weeks ago, Mona Hess, the project’s 3D digitisation specialist, visited the BPMA to undertake trials of low-cost scanning and photogrammatery techniques.
In conjunction with our Conservator, Krystyna Koscia, Mona tested the application of a cyclododecane spray – a substance which, when applied to objects, makes them easier to digitise with a laser–scanner.
Cyclododecane spray applied to test objects.This substances evaporates shortly after application and makes the object easier to scan with a laser.

The main event of the day was the photographing of a large printing plate against a target background, from which photogrammetric measurement will be taken to create a 3D map of the plate. You can find out more about photogrammetry and other techniques we will be using in this post. The plate was also scanned using a low-cost laser scanner, to obtain a rough geometry of the plate itself. Other objects were also photographed and scanned, including a die, an embossing die, a slogan die and a roller.

You can check out the preliminary 3D model of the plate online now, and manipulate the model. We promise that the final results will be more detailed!
Trials continue in May, when Mona will be using the laser-scanner at UCL to scan other key objects from the collection.
