Adelaide's Overwidth STA Buses.

Postby Denv12 » Tue Jul 24, 2018 9:28 am

Buses of both MTT and STA Adelaide at the time were overwidth by 1 and a 1/2 inches.Each side needed to be reduced to get the width down to the 2500mm legal width. Leyland Worldmasters,AEC and the Volvo B59s were overwidth. Some vehicles were narrowed down including Phil Denton's fleet,1 bus converted for ABC by Edwardstown company Smiths and at least 1 was converted by Smiths again that was sold to Smekel's on the Gold Coast. How many other buses were narrowed? Thanks.

Here's an earlier post showing Volvo B59s.

MTT buses built between 1954 and 1963, essentially to replace trams and trolley buses, were built to a width of 8feet 6 inches.

These were the 140 AEC Regal 1Vs, 169 Leyland Worldmasters, and 30 AEC Regal V1s.

At this time, the legal width of a motor vehicle in SA was 8 feet, so these buses, at that time, were 6 inches overwidth.

In the mid 1960s (1967 springs to mind, but don't hold me to it!), the legal width was altered to 8 feet two and a half inches (I think this was the legal width in other states), so they became only 3 and a half inches overwidth.

Incidentally, the two underfloor prototypes (the AEC Real 1V 240, later rnumbered 600, and the Daimler Freeline, 166) were built to 8 feet 2 inches, so they were 2 inches overwidth for most of thei lives, but becamed legakl width in the mid 1960s!

Subsequent MTT/STA buses up until 1983 - namely the Daimler Roadliners of 1969, the first and second series AEC Swifts, 1970-1978, the Volvo B59s, and the first 70 MAN Sl200s (1801-1870) were also built overwidth.

Most of the Leyland Worldmasters were narrowed upon sale to interstate bus companies between 1972 and 1979, along with many 700 series AEC Regal 1Vs, a smaller number of 600 Regal 1Vs, and several of the Regal V1s

Buses from these groups which remained in SA were generally given permits to run overwidth, particularly for MTT licensed operators.

Other operators in SA were at the whim of the Transport Department - at times, they would issue permits for use on a specific route only (such as a school run), at other times, to operate within the metropolitan area only, and various other restrictions.

I contemplated purchasing some verwidth buses, and applying for a permit, but felt the risk of being stranded at short notice with a vehicle that could be used only under restricted circumstances, or even not at all, was too great. I eventually purchased buses which had already been narrowed for interstate operators, and brought them back to Adelaide.

The earlier batches of three-door vehicles had particularly strongly built bodies, and the processing of narrowing them was quite involved.

The later AEC Swifts, particularly the 400-600 series, were able to be narrowed much more easily. This was also helped by Queensland being prepared to allow them to run in the overwidth form, the same applied to the Volvo B59s.

I don't think many, if any, of the Daimler Roadliners were narrowed, as they had a poor reputation for mechanical reliability.

I am not aware of any MTT/STA buses which were one and a half inches overwidth.

Cheers, Trevor

Thanks Trevor for the reply. Thats a lot of research there.I'm thankful for your reply.Its good to see those buses did get see service as is.

Sorry.I think I meant the total overwidth of 3 inches.
