I suspect TV / radio geeks on this forum might be interested in the segment on the Westerglen radio transmitter site on tonight's Great British Railway Journeys, featuring our own Tony Currie
Nice little piece. I suspect Tony might be disappointed with how it was edited, so his answer to "How much power?" came out as just "a lot of power", which I'm sure was the end of a more detailed answer.

It wasn't half as dumbed down as I expected it to be. Freeze framing some of the close up shots of the equipment reveal some marvellous BBC home brew devices from the last century still in use
It wasn't just me looking at the kit in the background then!
I suppose if anywhere in the industry has older items that are still in use, then an AM transmitter is probably one of the most likely places to find them.

Indeed ! There was one crate that seemed to be using MSF on 60 kHz as a check source for the rubidium drives ?
Yes in the old BMM chassis, there was a lot of my life spent working with those.
The meter with the ring of LEDs reminded me of the audio phase meter we used when equalising stereo circuits. that also had the ring of LEDs and the readout of the value next to it. Putting the ring on there had been a suggestion by my boss to BBC Designs dept.
I was interested to see that the practice of dropping the incoming audio down to around -45dB remains, with the line amp to bring it back up the zero.
In the old analogue line days that would have been the passive equaliser in the double chassis, with the required attenuation, and then the +45dB amp.
Now as there is no eq required it is just a 40dB pad with the gain on the amp down a little.
I liked the various labelling of the INR services - Absolute, AKA Virgin, INR 2, R3. Makes chasing through the wiring fun when all the different vintages of diagrams have different labels for the same thing.
Sadly, Tony has announced that he’s not returning to work following his health scare last year. That’s sad news. He is a lovely man and I wish him and his wife all the best.
Tony Currie and Tony Hall stepping down on the same day! The BBC won’t survive.....
