Does anyone know which lines locomotives are banned from & those with a weight restriction?
67's are banned from the cambrian and can't do more than 110mph in normal service.
A pair went to Pwllheli earlier this year!
In my days on BR there was a thick booklet titled "Locomotive Route Availability and Restrictions" listing every diesel locomotive class matched against every section of line. That was just the Southern Region.....!
According to local legend, HST's are barred from using the Balcombe Tunnel on the Brighton Mainline - not sure why but apparantly they are.
171's can only use certain platforms at Victoria.
377's cannot turn left at Hurst Green (on the down) unless they get a really good run up![]()
And a 377 cant turn left at Hurst Green, mainly as the line towards Uckfield isnt electrified.

Unsure why HSTs would go onto the BML in the first place.
Dont believe 171's have gone to Victoria as the ventilation shafts for the diesel fumes are in a different place to the thumpers, which then lead to the Uckfield service being moved to LBG.

Off topic but when was the cambrian fitted with retb was it? I saw a picture of a hybrid class 150 at towyn on a machcellynth service in about 1990 and central ran 156's on it i believe.
Why are loco hauled trains banned from Wigan to Southport, knowing that in the 1990s Class 31s & 37s were regular visitors?
Also, why are Class 40s banned from the former Southern Region, when the likes of 40122 visited on Railtours?
I also heard a couple of years ago that 37s were banned from running the Caledonian Sleeper on the West Highland Line in places due to curve gauging issues and had to be replaced with 67s...or is it the other way around?
Other way around............37's have (for a main line loco) a good RA. 158's are banned from a number of lines in Scotland (including the WH).
I do believe that running any diesel or steam loco (and possibly even some DMUs?) into Stansted Airport is banned due to ventilation issues and an overly sensitive fire alarm.
Certain platforms at Stansted cannot take diesel locos due to the proximity of the fire alarms. This theory has been tested a few times after a 31 has run in on a test train, with hilarious results. IIRC, there's one road that a diesel can run into without setting off the fire alarms.
The above reason is why the extremely rare sight of 86101 and 87002 once top and tailed a radio survey train.
158's are banned from a number of lines in Scotland (including the WH).
And Pacers are pretty much banned totally from Scotland![]()
158's are banned from the west highland because they have no retb system. Did scotrail not get allocated some pacers but swapped them with 158's instead?

, also I believe 97301 missed out the Cwmbargoed branch during its testing of the Valleys the other month with the mentor coach & dbso i think, even though 37s used to run out of there regularly back in the day, and a few weeks before a 66 charter ran up there with a nice rake of mk1s! must have been the DBSO..
