Overhaul of G.W.R. 2.8.2. Tank engine 7200

(Im not sure if there may be another thread for 7200) This seems to be at quite a advanced stage now of been nearing completion of its overhaul at Buckinghamshire railway centre according to rail advent the cab watertanks and smokebox has all been refitted back on the running plate (it dosent say anything about the overhaul of the boiler though for this tank engine) does anyone on nat pres have anymore info on 7200? For more on this see rail advent if anyones interested.

I like this engine I had forgot about it. It will be grate when it’s running again.

The boiler is at HBSS. Check their site for updates.

 

And if you google HBSS you get all you need to know about Salt Solutions.
Could you supply a link that is accurate please?

 

They are Facebook only as far as I can see - no conventional website.

Thanks Tom

 

What is the biggest tank engine?

 

Arguably, Garratts are tank locomotives. That would make the U1 the largest (UK) tank loco.

 

Indeed, but the three surviving 72XX tanks must be contenders for being the largest surviving tanks in the UK.

Peter (fully expecting someone to prove me wrong)

 

Among types that have not survived, I think the heaviest tanks to operate in the UK (aside from Garratts) were the LNER Class S1 0-8-4Ts. The booster-fitted variant weighed 104 tons.

I am empressed by how big they it is. Which is why my question was there as I think they must be the biggest unless anyone had a bigger one to suggest. The pictures of this engine make the tender look really big compare to most engines

 

That’s a beast

 

You're not wrong there! The heaviest flavour of NER 8-coupled leviathans comes in over 15tons heavier than Watson's (GS&WR) less than impressive brace of 4-8-0Ts, the first of which entered service in 1915 (i.e. when Ireland was still part of the UK) .... and those monstrosities were 5'-3" gauge.

 

The 0-10-0T GER Decapod with 3 cylinders was the most powerful tank engine in the UK, but not such a heavyweight. https://en.wikipedia.org/wiki/GER_Class_A55

 

I've always had a fondness for the Beames 0-8-4Ts, which only came out in LMS days but really should be called a LNWR type.

You might favour the Londonderry & Lough Swilly 4-8-4Ts?

Back on the standard gauge, a number of very large tank engine designs were produced by British companies in the final Pre-Grouping years, but engineers subsequently stepped-back from pursuit of super-sized tanks. There were stability issues with some of the largest passenger tank types and braking issues with goods tanks. A large goods tank was a notable omission from the BR standard range. But some other countries carried on down the large tank path. The limit was possibly the Bulgarian 2-12-4Ts, which tipped the scales at 146 long tons in 2-cylinder and 152 long tons in 3-cylinder variants.

 

Yes, also a fan of the LLSR engines .

That Bulgarian loco is quite a beast....

Presumably axle load is the ultimate barrier?
