London Transport RT delivered to Kent

Last week I had my first half cab drive since March and it was a long distance delivery job for a new owner.

The AEC Regent III, 1951-built RT2591 (LYF316), came to Somerset in 2019 as part of a batch of purchases from the former Yorkshire Heritage Bus Company fleet. My friend Dave Moore and I had quite an adventure bringing this bus and a Wigan Leyland PD1 back (full story here).

Being suplus to requirements in Weston-super-Mare, RT2591 has now been sold to a gentleman in Kent so this was a solo delivery journey.

I hadn’t driven a bus with a pre-selective gearbox for several years so I had arranged to take the bus for a quick drive the previous afternoon, just to familiarise myself with it. Not the kind of task a driver can do safely when the bus is parked only 3 minutes from the motorway! Fortunately I recalled the required technique readily, helped by the fact that I’d watched several YouTube videos showing the driver in the cab of an RT. The thing to remember is that the pedal on the left (normally the clutch in a manual ‘box vehicle) is a gearchange pedal. A gear is selected in advance of actually needing it using the column-mounted selector. The pedal does the actual change when the time comes.

Confident that I knew my way around, I turned up before daybreak the next day to do my checks. It happened that there had been an overnight frost so my first job was to scrape away the ice on the cab windows! The 9.6 litre engine sprang into life readily enough but I began to get worried when it didn’t appear to be building up air. In the RT there aren’t any air pressure gauges. In fact the only dial in the cab is the speedometer! Instead, there is a metal ‘flag’ which hangs down in front of the driver when the air is low. Imprinted on the flag is the word ‘Stop’, making it abundantly clear that it’s not safe to move off. In this case, I couldn’t move off anyway because the gearchange mechanism is air-operated and I couldn’t engage any gear at all!

I revved the engine and waited for several minutes. Still no air. Time was ticking by and I was keen to get away as I didn’t know what delays I might encounter on the way. Not only that but my ticket for a return train journey had already been booked.

In desperation I sent a couple of messages and I soon learned that this particular RT is reluctant in the cold. A bit like me, in fact. The trick is to hold the gearchange pedal down while revving the engine. Lo and behold, within a few seconds after doing this, the ‘Stop’ flag withdrew itself into its box above the windscreen and all was well.
