Routes that I should think be converted to a 24hr daily service:
157: Change from a day route to a 24hr daily route, Places like Norwood Junction, Selhurst, Waddon, Wallington, Carshalton and Whrythe Green have no night services. so I'd definetley think this route should have a 24hr daily service and would also Connect with Night Tube at Morden on the weekends and a 24hr Southern and Thameslink at Selhurst Station also makes a connection between Crystal Palace/West Croydon/Wallington at Night.
56: Change from a day route to a 24hr daily route, gives Whipps Cross and additonal night service also connects with Night Tube at St Pauls and Night Overground at Dalston Junction.
75: 24hr daily service reintroduced to give places like Penge East and Lower Sydenham a night service, also connections between Lewisham/Catford/Penge/Norwood Junction/Selhurst/Croydon, and also connects with 24hr Southern And Thameslink at Selhurst.
289: Change from a day route to a 24hr daily route, I'd would consider this route being converted to a full double decker but it also gives places like Waddon Marsh, Lower Addiscombe Road, Addiscombe and Elmers End a 24hr service, speaking of Elmers End there is no night service there and idk why, also connects with 24-hr Southern and Thameslink at Purley
54: Change from a day route to a 24hr daily route, gives Beckenham Junction an additional night service and even Connects Woolwich to Catford and Lewisham via Blackheath.
293: change from a day route to a 24hr daily route, gives Epsom and it's hospital a night service and even connects with Night Tube at Morden.
257: change from a day route to a 24hr daily route, I pefer for the route to be a 24hr weekend service with Night Tube Connections at Walthamstow Central, Leytonstone and Stratford but does give a connection from Walthamstow Central to Stratford Station as 69 towards Canning Town does not serve Stratford Bus Station, and has a connection with Whipps Cross to Walthamstow Central and Stratford.
230: change from a day route to a 24hr daily route, gives Upper Walthamstow a night service, and night links between Whipps Cross/Walthamstow Central and Tottenham Hale/Wood Green, even connects with Night Tube at Turnpike Lane, Tottenham Hale, Blackhorse Road and Walthamstow Central also would partly replace the Victoria Line between Tottenham Hale and Walthamstow Central on Weekday nights.
388: change from a day route to a 24hr daily route, and would run every 15 minutes at night. along with 157 I'd highly consider that TFL should convert this to a 24 hour service as It serves Shoreditch which has alot of nightlife stuff like pubs, clubs, food places etc even a Night Overground service at Shoreditch High Street. also has extra links between Liverpool Street and Stratford at Night, with replacing the Central Line between Liverpool Street and Stratford aswell excluding Bethnal Green, connects with Night Tube at London Bridge, Liverpool Street, Bethnal Green and Stratford (altough serves Stratford City at night), and also connects with and overnight Southern and Thameslink service at London Bridge when there's no Southern service to Victoria and Thameslink between East Croydon and Bedford.
161: change from a day route to a 24hr daily route, gives Queen Elizabeth Hospital/Chislehurst/Mottingham an overnight service with a connection to Woolwich and North Greenwich also Night Tube at North Greenwich aswell.
422: change from a day route to a 24hr daily route, connects North Greenwich and Woolwich via Blackheath, Royal Standard also via Plumstead and Bexleyheath.
51: change from a day route to a 24hr daily route. tbh, Orpington needs more night services bc N199 only serves Orpington at night, 51 is one of the routes that go to Orpington and also connects St Mary Cray, Sidcup, Welling and Woolwich also gives St Mary Cray a futher connection to Sidcup and Woolwich aswell.
358: change from a day route to a 24hr daily route. altough you already have N3 connecting Crystal Palace, Beckenham Junction, Penge and Bromley. but 358 gives a new night link between Crystal Palace and Orpington with a new night service at Eden Park.
185: change from a day route to a 24hr daily route. connects with Lewisham and Victoria and gives Forest Hill and Denmark Hill an extra night service, and also replace the Southeastern at night serving Victoria, Denmark Hill and Lewisham.
197: change from a day route to a 24hr daily route, gives a connection from East Croydon to Norwood Junction at night and also would be a direct route from Penge to Peckham without having to change routes with 24hr routes 12 and 176, also connects with 24hr Southern And Thameslink at East Croydon.
127: change from a day route to a 24hr daily route, I'd like how there's a connection with Purley to Tooting Boardway, I'd consider 127 having a 24 hour service as it connects with Night Tube at Tooting Boardway and 24hr Southern and Thameslink at Purley.
151: change from a day route to a 24hr daily route, Sutton needs more night services aswell as it only has 213 and N44, so to get the elephant out of the room, there we have 151 as it connects with Worcester Park at night and also has a connection from Sutton Hospital and gives Hackbridge an overnight service.
154: change from a 24 hr weekend service to a 24hr daily service, this route would partly replace the Southern all nights between West Croydon and Sutton, and gives Sutton a connection to Morden and West Croydon, and will also bring back the links with N213 between Sutton and West Croydon.
X26: change from a day route to a 24hr daily route, I'd would also highly consider TFL converting this route to a 24 hr service, it gives an additional connection from West Croydon to Sutton via Carshalton and also Kingston, which would also bring back night connections from the N213 between West Croydon and Kingston via Sutton, and also will have an quicker service at night between Heathrow and Kingston instead of using 285.
50: change from a day route to a 24hr daily route, this gives places like Clapham Park, Norbury and Thronton Heath extra Night Services and also will have a new night link between Stockwell and Croydon. Via Streatham, Clapham Park, Norbury, Thronton Heath.
278: change from a day route to a 24hr daily route, gives West Ruislip a night service and a new night link between Heathrow and Ruislip.
275: change from a day route to a 24hr daily route, gives Woodford an extra night bus and connects with Walthamstow Central along with Barkingside.
