We haven't been to China recently but we have been busy. We have finalised the artwork for all Rail Tank Cars.  See our wallpaper below for some of the many colourful versions that we are producing. Once the factory returns to work after their New Year holidays we'll update our delivery schedule. 

The OCY is also nearing production, the last two mods we requested have been finalised and we hope to get a production slot shortly with a projected delivery date in the middle of 2012. 

The BMF milk tank project has progressed to tooling with the first expected samples due around late April. This compact bogie wagon will be done in four distinct OAK liveries, many thanks to one very observant follower who located a picture of a white one trailing a Garratt on the Main North.

Tulloch 10,000 gallon Rail Tank Cars

The tank car project was to be the first SDS bogie goods wagon. The design brief incorporated the use of a standard NSWGR riveted tank car underframe, two styles of bogie, and two styles of dome and tank barrel.

We thought this was a fairly straight forward, however after several weeks of questions from our suppliers we quickly came to the conclusion this was a more complex design for them than it seemed to us. 

SDS had also provided our suppliers with the OCY data package. There were fewer questions being asked about the design of container flat than the tank cars. SDS took the opportunity to concentrate our supplier’s efforts on the development of the OCY model whilst we focused on the more specific details on the individual Tulloch tank car variants. The OCY project came together extremely quickly and we decided to proceed to tooling immediately. 

After an intense period of design SDS commenced tooling for the tank cars in September 2010. Each tank car model is made up from over 140 parts as shown in the diagram on the left.

SDS is producing two styles of Tulloch 10 000 gallon tank car. Some of these cars had a service life of over fifty years, most received several repaints and some had several owners during their colourful history.

Our choice of the  NSWGR riveted tank car underframe provides us with an option of producing further styles of tank cars at a later date. Here are some examples:
