Brunel’s great arched roof is to many people the epitome of Paddington Station but this was not built until 1854. The passengers who first travelled on the line from Paddington to Maidenhead, which opened on 4th June 1838, started their journey from a far less imposing structure – little more than a collection of wooden sheds.

 

A London terminus for the GWR was needed in a hurry, after negotiations with the London & Birmingham Railway for a joint terminus at Euston broke down. With the line to Maidenhead almost ready, the GWR Directors desperately needed to start generating passenger revenue and, since authorisation for a route into Paddington was only agreed by Parliament on 3rd July 1837, there was no time for grand designs!

 

A quick solution was to build the station offices into the arches of the new Bishop’s Road Bridge and provide simple wooden platforms to the West of this bridge. Goods facilities were established on the other side of the bridge, alongside the Forecourt from where passengers entered the booking office, under one of the arches. The great artist of early railways, J.C.Bourne, produced a lithograph of this façade of the station. I have annotated the locations of the passenger facilities on his illustration, as shown below:

I have not found any early illustrations of the layout of the platforms beyond the bridge but there are several early drawings, mostly in poor condition, that provide plans of the tracks and platforms, as well as details of the platform canopies. A selection of these drawings is available on-line, in the ‘Historical Engineering Collection’ of the Network Rail Corporate Archive (NRCA).

 

3D Station Drawing

 

I decided, as an experiment, to see whether I could use ‘Fusion 360’ to create an impression of the original station by using the techniques of extruding from drawings, just as I have done for my models of rolling stock.

 

The NRCA drawings include sketches of various alternative proposals, from which I chose the plan view in NRCA161183 as a suitable base from which to create a 3D model. First of all, I had to digitally ‘clean’ the original drawing to create my working version, shown below.

There are many features of the track-work that seem strange to modern eyes. Note, in particular, the widespread use of wagon turntables and traversers for moving the small carriages and wagons of the time between tracks. Several tracks ended in carriage loading ‘shoots’ at the end of the central carriage road, between the Arrival and Departure platforms. This arrangement is shown in a lithograph of, Slough Station by J.C Bourne, of which I show an extract below:

I also found a less detailed re-drawn plan of Paddington Station, which provided the all-important scale, in the book ‘Paddington Station - Its history and architecture’ by Steven Brindle, published by English Heritage 2013.

 

With this additional information, I could import the NRCA plan into ‘Fusion 360’ as a canvas and use the ‘calibrate’ command to adjust it to the correct scale. I decided to work directly in ‘feet’, since these units are used throughout the NRCA elevation drawings.

 

Bishop’s Road Bridge

 

My first 3D extrusion in ‘Fusion 360’was from the plan view of Bishop’s Road Bridge (shaded pink in my annotated version, above). Initially, I extruded the rectangular ‘body’ to a height of 30 feet. I then compared my structure, marked with the locations of the various arches, as indicated on the plan, to check the proportions against the Bourne lithograph. (It is known that Bourne used a ‘camera obscura’ as a drawing-aid, so I was confident that his illustration is accurately proportioned.)

 

Steps in creating my model of Bishop’s Road Bridge

 

Once I had made sketches by tracing over the Bourne canvas, imported into ‘Fusion 360’, I could overlay these sketches onto the face of my rectangular Bridge ‘body’ and extrude the various arches.

 

Platforms

 

Details of the platform canopies are shown in drawing NRCA161326, of which my ‘cleaned up’ version is shown below. This drawing shows the end elevations of the canopies over both the Departure and Arrival platforms, together with details of the cast-iron support pillars.

 

My ‘Working copy’ from NRCA161326

 

As before, I imported this drawing into ‘Fusion 360’ and sketched the outlines of the roof trusses. I also created a model of a single pillar by drawing over the profile and then using the ‘revolve’ tool to create a cylindrical ‘body’, as shown below:


Using ‘Revolve’ in ‘Fusion 360’ to create 3D-model of Pillar

 

Once I had a single model of a pillar, it was simply a matter of using the ‘Pattern on Path’ tool in ‘Fusion 360’ to create the array of pillars shown on the NRCA plan of the platforms. Note that I have raised the platform surfaces and carriage road by 3 feet, above the level of the track bed.

 

My 3D-model of the Arrivals Platform with Pillars and a single roof truss

 

I was very pleased to find that the dimensions derived from the elevation drawings corresponded very closely to those derived from the plan view, indicating that my ‘calibration’ in ‘Fusion 360’ had been successful. After duplicating the trusses as required, again by means of the ‘Pattern on Path’ tool, I added roofs by extruding from the profile set by the trusses at one end of the structure.

 

The end result of this stage of my modelling is shown below:

Of course, the advantage of having a 3D-model in the computer is that I can choose to view it from whichever direction and in whatever detail I choose, for example:

 

View across my model of Paddington Station from above the Forecourt.

 

The above view demonstrates the sharp angle between the platforms and the approach road, by which passengers arrived at the station. Carriages could proceed through the central arch to reach the carriage dock set between the Arrival and Departure platforms. At that period, wealthy patrons of the railway loaded their carriages and their horses onto trains and, in some cases, chose to travel inside their own carriages, rather that the coaches provided by the railway.

 

Adding other models

 

Once the basic 3-D model was in place, I realised that it was perfectly easy to add some of my existing models into the scene. The ‘Insert Derive’ tool in ‘Fusion 360’ allows model data to be imported into a design from other folders already held in the computer. To demonstrate this procedure, I imported my existing models of Brunel’s Britzka and of a Carriage truck.

 

I realised that these models had been dimensioned in millimetres, as 4mm-scale models. When first imported, they appeared at their small ‘model scale’. I could, however, select these model bodies and use the ‘Scale’ command in ‘Fusion 360’ to increase their dimensions by a factor of 76, so that they conformed to the overall building model. After re-scaling, I could use the ‘Move’ tool to position them as I wished within the Station, as shown in the example below:

 

 

Loading my model of Brunel’s Britzka onto a Carriage Truck at Paddington Station

 

 

Taking this idea a little further, I imported some other models, including my Horse Box, a horse, and the locomotive ‘Vulcan’, to create the following scene:

Conclusion

 

As I wrote at the outset, this is all experimental and I have had a lot of fun exploring the possibilities of scene modelling in ‘Fusion 360’. I realise that I am venturing into the territory of digital ‘Train Simulators’, which @Annie demonstrates in her thread can be very impressive and allow you to drive the trains as well.

 

My own modelling has allowed me to bring to life some long-forgotten scenes and I intend to continue by re-creating some of the other buildings around the old Paddington Station. Apart from the offices within the Bishop’s Road bridge, there was also a remarkable ‘round-house’ engine shed, designed by Daniel Gooch, a Carriage shed and, on the other side of the bridge, the entire Goods Station, with sheds and offices.

 

I think all this can keep me occupied and entertained for some time to come 🙂
