'Trolleycar' was an Allied deception plan, subsequently named 'Trolleycar II', which could have been turned into a reality has the situation warranted it, for an amphibious landing on the coast of German-occupied Europe (November/December 1944).

Created and implemented by Field Marshal Sir Bernard Montgomery’s 21^st Army Group, the plan was designed to induce the Germans to hold back a sizeable proportion of their reserves, largely in the Netherlands, to counter a notional plan for General H. D. G. Crerar’s Canadian 1^st Army, bolstered by the fictitious British II Corps, to launch an offensive to the west of Arnhem in conjunction with seaborne and airborne landings by the fictitious British 4^th Army straight from the UK.
