Bit more modern, but 92s/373s were banned from the newly electrified Tonbridge line/BML in the early 1990s due to the signal inteference they caused.
The Tonbridge line was electrified as a backup Channel Tunnel route but the actual stock was banned!

Reference class 40s etc.

The 1-Co bogies was found to have a tendency to derail on 1 in 8 obtuse (diamond) crossings. This led to several things occuring. 1 in 8 obtuse crossings were removed and replaced with either 1 in 7.5 crossings, switch diamonds (rarely), or single lead ladders (commonly). Alternatively, 1-Co bogies would be banned over those crossings.

Reference 9Fs,

Crossing wing rails in the UK were normally level with the running surface, unlike continental Europe where raised wing rails give better wheel location. 9Fs have a flangeless centre driver which is wider enabling it to ride over a level wing rail without dropping in the gap.

With the end of steam, an opportunity was seen to use raised wing rails in the UK if needed BUT 9Fs would have to be banned to avoid accidents.

I am not sure what the current situation is with either raised wing rails or the running of 9Fs.

I'm reliably informed that there are 2-10-0s in Germany with flangeless centre drivers, which are still allowed on the main line.

I've read somewhere about a Hall in steam days that somehow got used to go somewhere in the East Midlands or there abouts and had some close shaves with platforms, I think it even scratched up it's cylinders.
That would be the Grange which made it up the GC main line quite happily (and was indeed fully authorised as Halls and Granges were diagrammed to work as far as Leicester on a daily basis, and permitted to Nottingham Victoria), but successive sheds claimed to have no replacement loco, so made its way past Nottingham into forbidden territory. The damage was done when it got onto ex L&Y track between Penistone and Huddersfield, and platform copings and cylinders were damaged. Huddersfield shed was then stuck with it for some time until it was specially authorised to be towed dead and out-of gauge to Manchester. Once through Manchester Victoria all was well again as they were permitted between Exchange and Crewe, where they met ex-GW metals.

As I heard the story it was not do do with sheds having no replacement locomotive - control simply assumed (by this date, late in steam days) that the loco 68XX was an EE Type 3, and just let it carry on with the train.

I think you could be right. All the remaining loco hauled trains on the South Eastern Division went to/from Victoria.

Cannon Street also saw loco hauled trains banned for a while following the signal box fire in 1957. Temporary signalling arrangements made it very difficult to deal with shunt moves. This resulted in the Hastings DEMUs being rushed into service a couple of months earlier than planned.

I have read, but not seen it confirmed, that some restriction into Holborn Viaduct station - probably weight, I assume - was the reason that up until 1962 one could still see ageing 2-cyl 4-4-0s, ie Ds, D1s, Es, E1s, Ls and L1s on passenger duties in London.

There certainly are, but that is not to say that the design of the wheelset and its interface with the track is the same as UK practice.

Of course many locos were banned from many routes if their axle weight exceeded the axle weight for the particular line. This remains so on some lines todate.

Ex-GWR locos striking their cylinder casings on "foreign" routes was nothing new - Old Oak Common had to deal with this regularly after summer trips down the West London to South Coast resorts. The myriad routes possible through Kent were a particular issue. Exacerbated by the quite mid-range 43xx, a WR go-anywhere type, having the maximum 18.5" cylinder diameter, so as big as anything. The Southern put some effort into clearing routes like Reading-Redhill specifically for them, but odd sidings and especially curved platforms could catch them out.

I certainly remember Taunton stalwart 4932 Hatherton Hall being on shed with scrape marks down the left hand cylinder cover. Nobody would admit when it happened ...

There were other issues as well. When the Royal Train came over Taunton-Barnstaple in the 1950s, preparation was immense. Taunton's like-sounding 43xx twins 6327 and 6372 were sent to Newton Abbot works to be repainted green, but the big spindly viaducts on this route, which saw these locos every day, were banned for double heading. So the train stopped at the approach to each, the first loco was detached and ran across, then the second loco brought the train over. Reattach, on to the next one.

There was interesting discussion of 40s and Peaks being banned from Glasgow Central after derailing on the curves and complex point work, presumably on account of their length:


Are there other instances of locos being ‘banned’ for such reasons?

How did it operate in practice: was the ‘banned’ loco never put on a train at the start (eg Glasgow bound), or maybe a 40 was changed, say, at Carlisle for the last leg into Glasgow?
I am going to be silly and suggest Sarah Siddons is banned from going down tube tunnels

I seem to remember that LMS Princess Coronation class 6233 is now banned from the Harrogate line after starting a fight with either a platform edge or a bridge wall (can't remember which)!

The Grange would have been OK between Manchester Victoria and Chester, rather than Crewe. The line from Warrington to Chester was bullt by the Birkenhead Joint Railway which was LNWR/GWR joint, and the GWR had running powers over the LNWR between Warrington BQ and Manchester Victoria. The GWR didn't operate between Warrington and Crewe.

Close encounter with a bridge.

Which reminds me of 37s with roof horns being banned between Barnsley and Kirkgate due to tunnel clearances, but ok for those with their horns in the nose, and if memory serves me correctly restrictions on 31s too.

Remember going on a railtour with a 37 with horns on roof (may have been 229) and ended up in n a big diversion due to this.

Blackfriars Bridge(s) was the problem.

More modern, but I have a feeling Mk3 (and derived multiple units) is banned from the Oxted line due to tunnel clearances.

Not a ban per se, but diesel trains have to take care through Glasgow stations, as laid out in the Sectional Appendix.

NR Sectional Appendix said:
DIESEL TRACTION PASSING THROUGH GLASGOW
QUEEN STREET LOW LEVEL, GLASGOW CENTRAL
LOW LEVEL AND ARGYLE STREET STATIONS

Diesel traction must specifically NOT draw power when passing through any of the above stations, from either
direction.
Signallers must ensure that, where possible and practicable, these trains are regulated accordingly back at
either Partick or Rutherglen such that they can coast through on clear signals.
The Train Running Controller must also remind train crews of this instruction prior to passing through any of
the above stations.
The reason for this instruction is to avoid the unnecessary activation of the smoke alarm at the above stations.
A recorded example of this going wrong (not my video!)

There's quite a lot south of London where clearances aren't enough for 23m stock. That's the main reason most EMUs were 20m until recently. There are very few routes away from the third rail network that are similarly restricted, although I believe some are in the Cardiff Valleys.

How does that work with the Fort William sleeper, as that is routed via and calls at Queen St Low Level?

Slight problem if e.g. Charter trains might have a crew change at Glasgow Central Low Level or the train receives a yellow aspect followed by a red.

Presumably in cases like this, a Diesel loco has to take power through the low level tunnels

Used to cause problems when the RHTTs were 37s. They’d start out alright, then there’d be a swap and it’d always be one with roof horns.....

There's a restriction under a bridge on the Lea Valley lines where 37s with roof mounted horns are banned, therefore any trains using that particular side of Liverpool Street have to be hauled by Splitbox 37s with nose fitted horns

That may have been the theory, but 37s with roof mounted horns did sometimes work on Cambridge line services. I recall having (at least) 37198 and 37273.

The run from Euston to Edinburgh via the WCML is done with a Class 92, ie. an electric locomotive, but when the 73/9 diesel is attached at Edinburgh (and would go through Queen Street), you're right, that might create an issue. I'll have to look that up!

I reckon that usually, signallers will hold diesel locos at Rutherglen (3 miles south-east of Central and Argyle Street) or Partick (2 miles west of Queen Street, Argyle Street and Central) until they have the road clear through the low level station and out the other side.

You could still get roof horn 37 s on Cambridge trains, but they were diverted via Southbury to avoid the restriction.on the main line.

Neither of these went via Southbury. I had 37198 from Ely to Liverpool Street, and 37273 from Liverpool Street to Audley End. I would need to locate note books to check the dates, but probably late 1970s or early 1980s.

Likewise I had 37184 on a Norwich - Cambridge - Liverpool Street which ran main line, seemingly without causing any issues. On the other hand I also had 37261 Cambridge to Liverpool Street, and the driver advised the signaller before departing from Cambridge that it was a roof-horn loco, and we were duly diverted via Southbury.

Pure speculation, but perhaps one or two locos had misaligned horns, which caused a problem, so someone assumed that they would all cause the same problems ????

I've been on several railtours returning from the WHL and been held in the tunnels near Glasgow Central Low Level and the pair of 37s have thrashed at full bore through the platforms leaving a nice cloud of clag lingering, the other occasion was the visit of 31146 and 31166 to Fort William and we thrashed through the platforms deafening the passengers

That must have been fun! I guess they must've done something about the smoke alarms since 2017 then - cause that would definitely have set them off if a 37 on a test train can!

On the subject of diesels down in the Glasgow low level suburban lines, all in more recent times (all from the RoyTheMouth YouTube channel):





When was the last time a pair of 20s worked through Queen St Low Level & Charing Cross with a passenger train of any kind (or with any train period!), never mind bonnet first! And that one of them idling at Argyle Street gives credence to their 'Whistling Wardrobe' nickname; honestly sounds like a 40 down there!
