Sidgreaves - MD} ORIGINAL DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}4/M22.8.28. re. INDIA 3. X5770 [Struck through: X5380] In view of experiments which you have made from time to time, which shew that the direct vertical deflection of the individual side channel of the 'twenty' is very small over the tie-bar portion, we wish to omit tie-bars for the present from India 3. They were first added to the 'twenty' on 5-G-2. when scuttle and dash movement was great, and tests later shewed that they had little effect- see F52766. The cross in the frame we believe to be the real XXXXX cure for the frames' maximum and most dangerous deflection, and to compensate for the added weight of the cross we wish to delete the tie-bars.
