Not into the heart of the Lake District, no — but the Caledonian Sleeper gets you to its northern edge. The 'Lowlander' to Edinburgh and Glasgow passes through Cumbria overnight and calls at Carlisle, on the northern fringe of the region, so you can alight there from the sleeper. What it does not do is stop at Oxenholme, Kendal or Windermere, the usual gateways to the central Lakes — so Carlisle still leaves you an onward journey to Windermere, Keswick and the high fells. For the central Lake District, the more practical route is a daytime train to Oxenholme (the 'Lake District' station on the West Coast Main Line, about two hours forty from London Euston) and a connection on to Windermere, or to Penrith for the northern Lakes and Ullswater. The sleeper genuinely suits travellers heading further north into Scotland rather than those whose destination is the Lakes proper; only Carlisle-based or northern-Lakes trips really make the overnight worthwhile. If Carlisle works for your plans, check the live timetable to confirm seat or berth availability to that stop, as arrangements and fares vary by night. In short: no direct sleeper to the Lakes, but Carlisle by sleeper, or Oxenholme and Windermere by day, are your two routes.
