Hi I have a question about the new Auscision Tait model release.
There are two basic varieties - earlier sets with spoked wheels, and later sets (with solid disc wheels)..
I only recall seeing the TAITS with disc wheels as a kid in the late 70's and 80's though I must admit I didn't give it much thought..
My question is when did VR change the wheels of the Taits over to solid wheels?
Were any TAITS still left around in the 60's and 70's with spoked wheels?
Why did they change them?
I've searched hi and low on line and can't find the answer...
Also I can't tell from pictures what sort of Wheels the TAITS have that are being restored right now at SteamRail
Does anyone know the history of this important wheelset change?
I was still at Eltham Depot when the Taits were withdrawn. Up till then I walked along side them doing a start up inspection many times. Part of this inspection was to check condition of wheels and brake blocks
I can say that I don't ever remember seeing disk wheels on a 1:1 Tait.
And if I do purchase a Tait it will be spoked wheels for me. The Taits were removed from Eltham soon after the underground opened. Although Eltham did run them through the Underground for a short time, until risk assessment worked out that these things burnt with such intensity that they would be a death trap in enclosed spaces, especially as the tunnels are fed with huge amounts of air from above. Interestingly the Taits survived much longer than the Blues which first appeared around 1956.
EDIT Also, as Taits came to the end of their lives when the Harris was introduced, Bogies were reconditioned and traction motors were rewound and altered to run on 600v to match EMD generators and control equipment.
These rebuilt bogies were then placed on Clyde built Y Class diesel shunting engines. The story goes that the VR was starved for funds at the time and could not pay for the 75 engines needed. Government funding is divided between new capital investment and general maintenance. By building the bogies and sending them to Clyde, (paid for under maintenance) they had sufficient Capital Finance to pay for the rest of the engines. The bogies were a huge success and did a magnificent job speed limited to 65km per hour. However if roller bearings were fitted, 100kph was allowed.
ALL Y Class bogies were fitted spoked wheels.
So perhaps the solid wheels only arrived under Tait heritage ownership? Just saying
